People aren't "banned" for whatever they say in in the forums unless its threats and the like. If someone continues to break the TOS (and I'll say it again, TO which they agreed) by continued negative commentary and that is ALL they are here for to try and stir negativity, then after attempts to communicate with them and it still doesn't work they will be banned.  Especially when we continually get complaints from other members that this trouble stirring member is affecting the time they are trying to spend here enjoying, it becomes a real problem. 

And unfortunately we all know there are people in this world that thrive on this type of behavior and I feel really sorry for them but we have to enforce the TOS when its warranted.
