Wow, you are an ignorant one. But, still, I guess we all deserve to know. The following are reasons why you may have been suspended or banned: 1) Disrespect towards anyone who doesn't deserve it will get you an automatic suspension, and if you are REALLY, REALLY disrespectful, you will be banned... FOREVER!
2) Major major RPG will get you an automatic suspension of 2 days or more.
3) Flooding and/or spamming (4 messages in a row TO YOURSELF) will get you 1 or more days of suspension. (suspension time depends on how much you flood or spam) BE CAREFUL: Between posts, wait and see if anyone replys. And if not, just leave and come back later if you're tempted to talk to yourself.
4)Coming back on a different account after suspension will earn you 2 more days of suspension on your main account each time you come back. HA! So stop it and just take your punishment like the weener you are :-) (erm, i mean WINNER!)
5) Cussing will not get you suspended unless its directed towards someone in the guild. Be careful, though, because the Neopets Staff is watching.
6) Being outragiously annoying is something that nobody likes. You will be suspended for this until you learn your lesson.
7) Begging to be unsuspended WILL NOT WORK. Don't even bother neomailing the council members. It will not work, and it may even get you suspended longer.
8) Quitting the guild and rejoining will definately get you punished longer. If it happens more than once, your suspension will turn into a temporary banning so quick it will make your head spin.
9) YOU know what's wrong. If you're doing something you KNOW is wrong, and its not on here, don't think you won't be suspended.
