My server has just suffered the most horrendous hack and griefing. I believe they accessed my console of remote host; they dumped logs and changed perms. Now that things appear to be as restored as I can, I'm worried because I keep getting the word 'allow' appearing straight after I do a command such as /spawn or /warp or on login; I can find no reference to this 'allow' beyond mention of command blocks. I've done rollback and with blockfinder, have searched for any command blocks; there are apparently none. So something has been changed in configs somewhere, or a gamerule perhaps, although the server's been restarted and it keeps happening. My perms seem fine again, although they had set the default group to be admin sigh. I'm really worried these hackers have set up something to let them come back. Anyone have any ideas to help me? I'm very anxious now.
