There was a mod once that banned everyone across all feminist/gender subreddits who was subscribed to /r/redpill once, based purely on potential toxicity. I was only subscribed to talk some sense into those guys, but instead I got banned from the very subreddits I was being a good contributor to (I was a Psych major and am interested in those things).

So as a result I simply unsubbed across all my Reddit accounts from everything and anything gender-related and everything that was not supportive or sex-positive, because it's an un-critically-thinking cesspool (actually, this criticism can sadly be levied at most of Reddit proper).
