there's many slayer scripts in development, hopefully one makes it to the sdn :p there's a lot of things to cover so only the developers with the most resources can actually make one
Hmm is that all the log says? If so, make sure you have everything setup properly, e.g. turn off resized mode (enable fixed mode), start script while logged in (if any problems)
otherwise, just paste the entire log
Unlucky if it was a 2 day ban then you must've got sniped by a jmod, make sure to speak every once in a while, or join a clan chat and babysit the bot if you are worried.
