Everyone makes mistakes online. The difference for a brand or a public figure is scale: a careless post does not stay in one feed, it gets screenshotted, quote-tweeted, and turned into a headline within hours. The cases below are not internet rumors. Each one was widely reported at the time, drew a public response from the people involved, and left a lesson that still applies to anyone running an account today.
We have grouped them by the type of mistake, because the same error keeps repeating under different logos. A campaign joins a serious conversation it never read. A scheduled post lands at the worst possible moment. A single tweet from one person becomes the whole story. Read these less as a hall of shame and more as a checklist of what to slow down and double-check before you hit publish.
The pattern in one line
Almost every fail below comes down to one of three things: posting into a sensitive topic without reading the room, automating or scheduling content that ignores real-world events, or letting a single account speak with no second set of eyes. Build a process around those three, and you avoid most of what follows.
Mistake 1: Hijacking a serious conversation
The fastest way to turn a marketing post into a scandal is to attach your product to a tragedy or a social movement. These three brands all did the same thing: they saw a trending hashtag or a news event and tried to ride it without understanding what it was about.
Kenneth Cole and the Cairo protests (2011)
As pro-democracy protests filled Cairo during the Arab Spring, the fashion brand's namesake chairman tweeted: "Millions are in uproar in #Cairo. Rumor is they heard our new spring collection is now available online... -KC." The reaction was immediate. Twitter users called it tasteless and pushed a #boycottKennethCole hashtag, and the company deleted the tweet and apologized within hours. Cole later admitted he had personally written it. Two years on, he posted a similar joke referencing Syria, which suggests the lesson did not fully land.
The takeaway: A live humanitarian crisis is not a marketing hook. If a hashtag is trending because people are in danger, your product has no place in it.
DiGiorno and #WhyIStayed (2014)
After the Ray Rice domestic-violence case, writer Beverly Gooden created the hashtag #WhyIStayed so survivors could explain the complex reasons people remain in abusive relationships. DiGiorno's pizza account, apparently treating it as a generic trending tag, tweeted: "#WhyIStayed You had pizza." The account admitted it had not clicked the hashtag to see what it was about, deleted the post, and then spent hours replying to individual users with personal apologies.
The takeaway: Read the hashtag before you use it. Ten seconds of checking would have prevented the entire incident. Trending does not mean safe.
Pepsi and the Kendall Jenner protest ad (2017)
Pepsi's "Live for Now" ad showed Kendall Jenner leaving a photoshoot to join a vague protest and defusing the tension with police by handing an officer a can of Pepsi. Critics, including activist DeRay Mckesson, said it trivialized Black Lives Matter, and many noted its resemblance to a real photo of Ieshia Evans confronting police in Baton Rouge in 2016. Pepsi pulled the ad the day after it launched, saying, "Clearly we missed the mark, and we apologize."
The takeaway: You cannot borrow the imagery of a real movement to sell a product and strip out everything that made it matter. Audiences notice when activism is used as a prop. The same caution applies to any brand building a presence on Instagram or TikTok, where this kind of misstep spreads fastest.
Mistake 2: Open-ended campaigns that invite the worst answers
Asking your audience to share stories or vote on something feels participatory. It also hands strangers a microphone, and on the internet, someone will always use it against you.
McDonald's #McDStories (2012)
McDonald's launched #McDStories hoping customers would share warm memories of the brand and its suppliers. Instead, the open prompt invited complaints about food quality, customer service, and worse. The company's social media director acknowledged within about an hour that "it wasn't going as planned" and pulled the promoted hashtag, but it had already spread, spawning the mocking spin-off #McFail.
The takeaway: Any open-ended prompt about your brand is a gift to critics if your reputation has weak spots. Run the worst-case version of the question in your head before you launch it.
Snapchat's "Would You Rather" ad (2018)
An ad on Snapchat for a mobile game asked users whether they would rather "Slap Rihanna" or "Punch Chris Brown," referencing the 2009 assault for which Brown pleaded guilty. Rihanna publicly condemned it on Instagram for shaming domestic-violence victims. Snap said the ad violated its own guidelines and removed it, but the damage was done. Snap's stock fell sharply that week, reportedly wiping out hundreds of millions in market value before partially recovering.
The takeaway: Ad-review systems exist for a reason. An automated or under-reviewed approval process will eventually let something through that a single human would have stopped cold.
Mistake 3: Scheduled and automated posts that ignore the real world
Scheduling tools are a normal part of running an account. The risk is that a post written days ago lands in a context nobody anticipated, with no human checking whether it still makes sense.
American Apparel and the Challenger photo (2014)
On July 4, 2014, American Apparel posted an image to its Tumblr tagged "#smoke" and "#clouds" on a fire-engine-red background, treating it as festive fireworks. It was actually a photo of the 1986 Space Shuttle Challenger explosion, which killed seven astronauts. The company explained that a young international social media employee, born after the disaster, had not recognized the image. It was removed after about 45 minutes with an apology.
The takeaway: Anyone publishing on behalf of a brand needs to verify what an image actually depicts. Cultural and historical context is part of the job, not an optional extra.
Adidas and the Boston Marathon email (2017)
Adidas emailed 2017 Boston Marathon finishers with the subject line "Congrats, you survived the Boston Marathon!" The wording was tone-deaf given the 2013 bombing that killed three people and injured more than 260, with survivors of that attack among the 2017 runners. Adidas apologized quickly, saying there was "no thought given to the insensitive email subject line."
The takeaway: Template language has to be checked against the specific event and place. "Survived" is harmless for most races and devastating for one with that history.
Cinnabon and the Carrie Fisher tribute (2016)
When Carrie Fisher died, Cinnabon tweeted an image of Princess Leia with a cinnamon roll standing in for her hairstyle, captioned "RIP Carrie Fisher, you'll always have the best buns in the galaxy." Reactions were split, but enough users found it a tacky attempt to ride a celebrity death for promotion that the brand deleted it and apologized. Notably, even a genuinely intended tribute can read as opportunistic when a product is the punchline.
The takeaway: A tribute that doubles as an ad is a tribute people will distrust. When you respond to a death, lead with respect and leave the product out of it.
Mistake 4: When one post becomes the entire story
Sometimes the account is fine and the process is fine. The failure is a single message from one person that travels faster than anyone can contain it.
Justine Sacco's pre-flight tweet (2013)
PR executive Justine Sacco, who had fewer than 500 followers, tweeted before boarding an 11-hour flight to South Africa: "Going to Africa. Hope I don't get AIDS. Just kidding. I'm white!" While she was offline mid-flight, the tweet went viral, was amplified by sites like Valleywag and BuzzFeed, and became the top trend on Twitter. Her employer, IAC, condemned it and parted ways with her. She landed to discover she had lost her job and become a global news story. The episode became a defining example in Jon Ronson's reporting on public shaming.
The takeaway: Follower count gives no protection. A single post can outrun you while you are literally unreachable, and "just kidding" does not neutralize the words in front of it.
Roseanne Barr and a canceled hit show (2018)
At the height of her ABC sitcom revival's success, Roseanne Barr tweeted a racist comment about former Obama adviser Valerie Jarrett. Within hours, ABC's entertainment president called it "abhorrent, repugnant and inconsistent with our values" and canceled the show. The network later relaunched it as "The Conners" without her character. Barr apologized and at one point blamed the sleep medication Ambien for the tweet.
The takeaway: A personal account and a professional reputation are not separate. For public figures, one post can end a project that employs hundreds of people, and no apology reliably undoes that.
Mistake 5: Losing control of the account and the audience
The last two cases show two different ways control slips away: an angry employee who still has the password, and a partnership that runs into a polarized audience the brand did not plan for.
HMV's live-tweeted layoffs (2013)
As the UK retailer HMV laid off staff during administration, an employee still holding access to the official @HMVtweets account live-tweeted the meeting to roughly 70,000 followers: "We're tweeting live from HR where we're all being fired! Exciting!!" Several follow-up tweets aired internal grievances before management regained control and deleted them, but not before the posts had been screenshotted and shared widely under a trending hashtag.
The takeaway: Access management is a real risk, not a formality. Know exactly who can post, and revoke credentials the moment someone is leaving, especially under tense circumstances.
Bud Light and the Dylan Mulvaney partnership (2023)
In April 2023, Bud Light sent transgender influencer Dylan Mulvaney a personalized can, which she shared with her followers. A sustained boycott followed from conservative commentators and customers. The financial impact was unusually well documented: in early June 2023, Modelo Especial overtook Bud Light as the top-selling beer in the US by revenue after Bud Light had held that position for about two decades, and weekly sales fell roughly 29.5% in the week ending May 20, 2023 (figures per the Bud Light boycott record on Wikipedia, as of 2025). The company's response, which neither fully stood behind the partnership nor clearly addressed it, drew criticism from multiple directions at once.
The takeaway: Influencer partnerships carry the influencer's full context with them, and a half-committed response can alienate every side. Decide what you stand for before you launch, then stand by it or do not launch.
A bonus case: the non-apology that made it worse
Not every fail starts with a post. Some are made worse by how the brand responds on social media afterward. When a passenger named David Dao was forcibly dragged off United Express Flight 3411 on April 9, 2017, and the video spread across every platform, CEO Oscar Munoz's first public statement said he was sorry "for having to re-accommodate these customers." That sanitized phrasing became its own scandal, ridiculed widely before Munoz issued a fuller apology days later calling the incident "truly horrific." United and Dao later reached a settlement on undisclosed terms.
The takeaway: In a crisis, the apology is part of the content. Corporate euphemism reads as evasion and extends the story. Plain language and clear accountability shorten it.
What these fails have in common
Strip away the specific brands and the pattern is consistent. The damage came from speed without judgment: a post that went out before anyone asked whether it should. A few habits prevent most of them.
- Read before you join. Click the hashtag, learn the event, understand the movement. If it exists because people are suffering, stay out.
- Add a second reviewer for anything sensitive. Tributes, topical posts, and ads should never be one person's solo decision.
- Pause your scheduler during news events. Automated posts that ignore the real world are a recurring source of disasters.
- Control access tightly. Know who can publish, and remove that access the moment circumstances change.
- If you get it wrong, apologize plainly and fast. Vague corporate wording prolongs the story; clear accountability ends it.
None of this means playing it so safe that an account becomes lifeless. The brands that earn trust online are usually the ones with a clear voice and a steady process behind it. If you are building that kind of presence, our social media guides walk through the fundamentals, our tool reviews cover the platforms that help you schedule and review posts before they go live, and our Facebook hub collects channel-specific advice for the platform where many of these stories played out. The goal is simple: move fast enough to stay relevant, and slow enough to never end up on a list like this one.
