The point wasn't that they were banning subs that had offensive content, it was that they were banning subs that were actively harassing individuals. In my opinion, judging by a rough timeline I have of events, the final straw was when /r/fph went after imgur employees.[0]

What I find funny about people complaining of censorship is that the sub in question would routinely ban people for saying positive things about the people they were trying to harass.
