@ J192: Nope, it isn't. PM is the worst choice in 99% of all cases. This is a good idea and there is not a single reason to keep it secret by using PM.
Is it a good idea to have a special thread for reporting and discussing these? I think it's pretty needless to have another thread whenever somebody spams their server.
Well, maybe there is just a kid who want to spam the CS2D's serverlist by hosting x servers with the same name at the same time. This is not for the first time and this case happened a month ago.
killall might not be a good idea, instead just remember process ID (pid), this way you can auto-restart specified servers without doing harm to other servers running on the same machine.
