People have complained forever about innocuous comments getting deleted.
The fact is that in order to gain moderator status, you must report a large number of posts that others also report as against the rules. So the most reliable way to gain moderator status is to start a sock puppet account to violate the rules and then report the posts of your sock puppet account using your primary account. Is it any wonder that trolls seem to control what ends up posted in comments?
Note: I am a person who posts on that site and never checks back again. That's not really a bad attitude to have.
