All the attacks on cmine.de originate from sweden, it's a guy running a CS server whose computer either has been compromised or who is absolutely stupid and has no idea on how to cover his traces.
Probably part of a bot net, the attack pattern tells me that it's just a stupid script being executed over and over again. Thought about reporting the IP address, but I don't want anyone to get in trouble for being stupid and messing around with my server, would probably be a waste of time anyway.
