I think this just about sums up the matter as far as Bustabit is concerned. Their ToS allow them to terminate accounts and though Perplex0 has a right to feel aggrieved about it (on the basis they feel they did nothing wrong), it does not mean they challenge the decision. By all means they can ask why and try to have the decision revered but since they did not receive a reply that satisfied them they should move on.

My advice to Perplex0 would be to put their energy and efforts in to something different. First of all, there are several Bustabit type of crash websites, maybe he should try playing there or basically if he is that determined he can use a new email address and IP address to access Bustabit after creating a new account.
