Can't you just ban orbitz from the listservers? That networkfilter is good and peerguardian increases the chances of him not harming a computer which runs peerguardian but he might just change his ip and also I think he found other methods how to crash servers that networkfilter cant block yet. Sonyk hosted a server protected by the network filter. The result was: Crashed by orbitz. Sonyk downloaded peerguardian and until now he is quite safe. But as I said before orbitz might just change his ip. Also it is annoying to run about 5 tools to play jazz2 properly (networkfilter, peerguardian and more e.g. seekerholefix, pc4, gamma, respawn or other stuff). I say just ban that silly guy from the listservers and bye. As some jazzer already said: We are getting owned by a 10 years old noob and some admins dont even care. Nimrod tried to push it but he failed - though he has been making progress recently. Also not everyone will be willing to run the networkfilter or peerguardian or other tools.
