Yes regarding Kicks you need to test if it works to disable Rangepickup, MobPuller and Teleport, because these can cause Kicks.
(non-Range) Pickup on 1x should be fine however
@GuterBotn1 It might be a side-effect that MobPuller causes more kicks and therefore problems.
It is 100% the pick up...
I've had accounts banned that had the pickup enabled.
Other character had pick up disabled and no ban.
All tests done in same area.
Edit: Teleport and frequent channel changing can be the cause of the problem as well.
Note that people who use free version of M2Bob get banned as well. They do not have teleport, or ranged pick up.
Some people on metin2 board reported bans for just using fraps.... it is possible that 3rd party applications get you now banned.
Normally all the bans have been at around 5pm strange enough...
