Don't know why there is so much secrecy surrounding bans..... In some of the other games i play they Publicly "Name and Shame" ppl on forums +Bans. and its a pretty effective way of dealing with cheaters and discourages a lot of players from doing it.
im not sure if this is the right place to discuss it but A lot can be done with chats too. a game i play...they almost dont need any mods for monitoring chat. if someone tried to spam they're warned automatically, 2nd spam offense is a 5 min ban and third time more than a day. same with swearing...the chat code automatically detects offenses and on the spot Bans,and announcement in chat.
ohh btw ive had the same experience with reporting push accounts on BETA server. firstly the mods took ages to act on it...and when it looked like he's been banned(all gbs and city deleted), the player returned after a few weeks/months and not only he got all his gbs back but also 10 levels on all gbs and 25+ levels on traz. now the account is inactive again, but we still dont know if the account has really been banned because of this privacy policy!
