Hmm. Nope. None that I know of. You'd have to contact one of his closer friends. He's nowhere to be found on IRC. I haven't seen him since he left IRC.
Have you spoken to legend about this? Tell him your nickname was hacked. And g:lines are not based upon nicknames, only real hostnames and IPs. So unless the opers are banning you on sight, (which I assure you they do not do at PS unless you were some kind of nasty spambot) then you should be able to come to #help and plead your case. The ban would only affect the person who stole your nickname. And maybe your vhost but that can be changed and the ban unset.
