Just for clarification:
The above mentioned player tried to connect about three times but couldn't get onto the server because of a pb hardware ban. Ten minutes later the player connected again with a new GUID and was able to play on the server.
How is this possible? I do not want an instruction on how this is being done!
I just can't imagine that a hardware ban can be circumvented by deleting the et-key.
Can we always be sure that a pb hardware ban is based on a cheat or can there be unfortunate circumstances in one's configuration to cause an (unjustified) ban? And even if so, is it really so simple to get on a server after 10 mins again without any inside knowledge of the whole matter?
