The reason behind the memes remains unclear, though several Twitter users have claimed they originated as an inside joke for LGBT tweeters. The reality of the situation is that the actress is not only an LGBTQ rights supporter but also an anti-bullying advocate.
The trolls posted the frightful memes during Pride month, and one of the completely fake Photoshopped images took off and got wide circulation.
Of course, it's always upsetting to see fan harassment make a celebrity feel so unsafe on social media that they wipe their accounts, but this situation is even more frustrating because Brown is a child.
Millie herself frequently posted on social media, updating on her whereabouts and posting sweet messages with boyfriend YouTuber Jacob Sartorius. While many of her followers loved it, others felt the image was too "old" for the 14-year-old. The hashtag had first appeared last November and has since resurfaced this month for Pride.
But there are some who say the memes started as an inside joke within the LGBT community.
"Users have taken to photoshopping incredibly vile and homophobic things onto photos of the star, because of irony", writes Vulture.
