That's a half-truth at best. There's a big part of the site dedicated to covering e.g. animal abusers.

The site owner seems to rarely promote that kind of content to the front page though, unless they try to get the site shut down.

If anything I'd say that's in favor of them.

Uh, no. I'm responding to the interpretation that the KW users generally want the people they follow to stop doing the things that make them worthy of being followed. ("Followed" here meaning "being talked about and having the things they do documented".) That's just not true, by-and-large.
