Well how come on the less lenient forums I am on compared to MTF, there's less arguments? I guess it might be the fact that users want to break the rules here, something like that, to look cool. Whereas rule breaking on a forum where you're less likely to get punished is pointless.
Well if you post on the Teletubbies forum, it's unlikely that people are going to insult eachother with rude words.
Seriously, I think moderation should be strict. We're here to talk about tennis and other things in a reasonable manner (which no doubt can be fun), not cause trouble just because we can hide behind an online alias.
