That actually happened much later. I am talking about examples like r/gundeals being removed, lots of accounts asking about it then getting banned, etc. Please don't try to imply that "undesirables" means just actually offensive or illegal behavior, though there was that on reddit too. Much like what the environment of a public bar would be: informal and varied.
It is not controversial to say that the corporate environment style social rules implemented in ~2015 went far beyond gnerally offensive content to the point where it was obviously catering to whims of the advertisers demanding they not be beside content their target demographics would just not like (ie, for political reasons or whatever).

> The move frustrated some commenters on the initial post. “Why is /r/fatpeoplehate banned, but /r/coontown get to exist?” asked redditor CrackheadControl. “That’s bullshit.” “Because the admins are fat, not black,” replied The_Wizard_of_Wang.
I think we can all agree that the above, and other mentioned subreddits were genuinely undesirable, no quotations needed. I was clear that wasn't what I was talking about. Your practice of just parroting these nasty people and their words doesn't actually address my point at all. Which was that it went far beyond just the nasty people to groups that weren't nasty and just made some advertisers uncomfortable.
It seems like you just want to point out nasty terrible people to stop conversation of if it was justification for doing bad things to everyone. That's a popular sentiment these days but it is wrong. Just because one group of people (or subreddits) in those punished by the authorities is actually nasty doesn't meant that all group of people punished by the authorities are.
