Seriously.
Rule of thumb for any community: If you're unsure what you're doing will get you banned or not, don't do it.
Doesn't matter if the rules are written or not. If you have doubts about the legality of whatever it is you're doing, probably shouldn't do it.
I say whoever has been banned lately due to unwritten rules, good riddance.
How half of you idiots act around new people should be bannable as well.
People don't want to know, that's why.
No, it's because that falls under the unwritten "2 cool 4 the internet" rule.
