That the corrupt TER goons aka TerAdmin and mods have access to and do read the Private Messages of the members and they have banned a few because of what is said on the PM.
They, teradmin and mods, read Private Messages and eavesdrop on people daily, not just if there is a legitimate complaint of harassment or the like. They use the info from PM’s for blackmail, bribery and so on.
There are also guys like GaGambler and LePetomane who posts under the alias JakeFromStateFarm who use pm to get personal info and then give it to teradmin who use it in corrupt ways.
