l2german is a gracia final freeshard based on l2jfree, so it should be no problem to bot on. I got the IP and tryed to run l2net on it but it doesnt work. to play there you need a client updater that changes your system folder (no change in host needed) if I log OOG i get:
11:32:56 :[loaded saved server list
11:32:56 :[loaded saved blowfish list
11:33:16 :[starting login Process
11:33:29 :[ERROR: crash: OOG Login thread
the ip is: 85.25.150.109:2105 so I think that it can only be a botprotection with the l2 folder of the players and not a server-side protection.
the side is: www.forum.l2german.net
Help would be rly great =)
