You aren't wrong, the problem with politely encouraging anything be it grammar/punctuation or proper sub forums are that you'll end up getting flamed by a bunch of people. Christ, you'll get flamed for giving someone crap about driving like an idiot or using questionable judgment. I'm not worried about being Mr. Congeniality but after a while it just gets really old.
I personally try to avoid using the report button after I found out how much stuff you guys have to sift through everyday on top of your regular jobs.... that has to suck.
It just all adds up to a less enjoyable experience as the people who can't or won't follow the rules seem to run wild. Meh, first world problems....
