As the Marvel Entertainment film Black Panther opened in the U.S. in February 2018, some social media users attempted to put a damper on the occasion by posting fake accounts of anti-white attacks only to be foiled by other users’ photo-sleuthing skills.

One photo posted on Twitter reportedly generated around 400 retweets before being debunked. The image showed a towel soaked in blood over a sink alongside the caption:

Was at the #blackpanther premiere but a group of black youths said this movie wasnt for me. I am white. They then proceeded to assault me. Im heading to the ER now.

But other users quickly noted that the picture was actually posted on the photo-sharing platform Flickr in 2009.

Twitter suspended the account behind that fake post, as well as the one that attempted to pass off a picture of a 19-year-old Swedish woman’s bloodied face. She was actually attacked at a bar in Malmo, despite false claims the photo was taken after an “assault” connected to the film, which features a nearly all-black cast:

Another user attempted to pass himself off as 23-year-old Michael Voller, who was hit in the face in London in May 2017 in an attack that was reportedly precipitated by anger over the results of a FA Cup soccer semifinal match:

There is no indication that these posts are coordinated, but another social media user passing themselves off as the victim of an assault — this one using a photo taken from a British makeup artist’s porfolio — showed off their “work” on a message board in the web site 4chan:

And yet another claimed in a Twitter post that his “older brother Kenan” suffered a ruptured eardrum after an attack:

But that account was also debunked by users who showed that the picture attached was actually taken from a story about an actual assault in Dallas, Texas.

Despite these types of smear attempts, reports estimated that Black Panther was on track to earn between $200 million and $205 million at the box office for its opening weekend.
