I have banned the following IP from all SCP related forums and servers, including fs2net and the lobby.
80.53.167.45
It is a user named Kuras, who, in the months preceeding PXO going offline, kept spam bots in the PXO lobby and tried to crash it.
His most recent exploits can be viewed here:

I would encourage SectorGame to employ a similar ban.
Sorry for the public post, but i have had it up to my eyeballs with this jerkwad, and I think it is time the entire FS community told him collectively where to go.
