Oh wow, it's back once again. Yeah, 100% fake.
The person behind that account has been doing the same stunt over and over for the past several years.
They always pop up using edited pics of different people, with a recognizeable style, pretending to be a girl with huge implants. They always try to get the most possible attention by posting on these general subreddits, because they always got called out almost immediately when posting on bimbofication subs. Kinda funny what some people will do to get their rocks off.
