To the GoonHub.com administrator: Your server is hacked

[unnamed]

In the meantime a fourth report has been added to the StopForumSpam database for that server IP, so it is continued to be used to post spam. I suggest to run netstat (assuming it's a Unix-based server) to check if there are any suspicious ports open. It could be either that you are running an open proxy without knowing, or even worse, someone could have compromised the server and is running their own software on it. In that case the only sensible thing is to reinstall the complete server because you never know how deeply the attacker nested their stuff into the system.
