It doesn't surprise me that the subreddit is banned. Self-identifying as an 'incel' inherently has a hugely rape-y vibe because the whole mentality on that sub is 'women are so evil cause they won't forget my 300lb neckbeardy ass'.
The global administrators probably got so many incidents of like brazen, unironic misogynism that they finally just decided to pull the trigger. Rest in pepperonis. Like the kind stuck to the ass of everyone that browsed /r/incel.
