Quote fromAnyways, to answer DeathMars' question (since he's one of the few members posting in here I actually feel like interacting with right now)...
What will earn you a ban...
Multiple Accounts w/o Explanation - Perma Ban (Never Expires)
Porn / Other Adult Content - Perma Ban
Trying to (or talking about) hacking this site - Perma Ban
Posting personal information about another user w/o their permission - Perma Ban
Being a spam/porn bot - This one is obvious. Perma Ban.
Requesting / Posting Hacks, Warez, Torrents, etc - Ban length will depend on level of infraction
Discussing hacks for Blizzard games with the intent of making it easier for the player or disrupt other players' gaming experience (discussion of modifications like Eastern Sun are OK) - Ban length will depend on level of infraction
This being said, other ordinary infractions can earn you a ban if you break the rules frequently enough. Essentially, if the staff decides that you warrant a ban, you will get one.
Hmm... Makes sense. But, like you said, I guess most of it is also based on how the moderators thinki about the offense, meaning if you make an April Fools joke about hacking the site it won't really be bannable. Or is it?
I noticed that starting fights wasn't there. Can trolling or "flaming" someone get you a ban? or is it one of those things you have to do a lot of to get a ban?
