It's an offshoot of r/deuxmoi, based off of Deuxmoi, a blog that posts celebrity rumors and sightings. But Deuxmoi was too "problematic" so the users branched off into their own sub, Fauxmoi, which is a catch all for celebrity news and gossip, especially when intersecting with politics. They made a big shit about sniffing out who was and wasn't supporting Amber Heard, Palestine, BLM, and now Harris... I'm talking literally refreshing the instagram posts of every celebrity they knew to see who liked posts in support of Heard or Depp they could make a blacklist of the latter.
So, terminally online, vapid women and self-obsessed faggots who are overinterested in pop culture... and they got really touchy a few years ago when an article came out revealing that those who are too invested in celebrity gossip are dumber than average, because knowing Taylor Swift's entire dating history down to the month and year makes them totally smarter than the average person!!
They are constantly in hysterics over every tiny thing, and I've always been genuinely surprised that they don't already have their own thread here because of all the content that could be mined. But probably too brainrot-inducing to follow.
