I can think of about 100 ways to defend someone without bypassing.. It was a bad choice of words, and I'm sure the person didn't learn their lesson.. Its only 24 hours, not really that big of a deal.
Causing or influencing another to commit suicide can land you in jail for murder. Before someone points out that murder is in the ToU, I'll point out that the ToU incorporate applicable laws, by reference, and do not permit the forums or WC to be used for an unlawful purpose. Furthermore, suicide is not at all funny, and the right of a player to tell others to do it is not at all worth fighting for.
Promoting suicide is a silencable/bannable offense. If anyone has any screen shots of the offender promoting such a thing then I encourage you to email it to support@athinkingape.com so action can be taken. I'm sorry you were silenced, but to me it sounds like the silence was justified due to a bypassing of the filter. If you feel you were unjustly silenced then you can also email support@athinkingape.com and appeal your case. I'm locking this thread due to the fact that publicly complaining about a silence is a violation of the rules of conduct and the terms of use. Any and all complaints need to go through the support team at ATA.
