Question expel

Hello, can anyone explain me how to expell players with packets?
I tried spamming party inv packet, but it only freezes players for few seconds.
I'd appreciate any hints. Thanks

well i also saw that working with an klick mako so no packets are realy nessesary. it can be that they set an maximum limit of requests maybe you should try to use trade/Party/duel all at once to kill the client
