Thank you, you're completely right, it was useless! So only one more thing:

I want that a message appears when the player get kicked, which is telling everybody why he got kicked:

"SYSTEM: Player %s has been kicked by the server (Repeating incorrect login-attempts)!"

I just don't know if I can create a variable for the player under this callback and then get his name, otherwise I would have done it by myself!
