EDIT 2: There was another one from http://www.dswp.de/echelon/clients.php? ... .73.18.133 ; however, this one moved differently and I’m pretty sure he was a different person. Chances are, we were flashmobbed by some griefer clan or somesuch.
After it became clear they can’t be banned, me and Humppa simply kept kicking them; I had Echelon pages with IP searches open, and whenever a refresh showed a new name in the list, I’d switch back to UrT and kick the motherlover, occasionally before he had time to load the map:-P
