Guid spoof aMenti?

Last night I was searching for a 3on3 on IRC I was qryed by someone by the name "cms" he gave us the IP + psw and we connected to the server. It was the aMenti war server #1. There where already two player on the other team. One of them was called "mystic" I dont like nicklamers so I did /guid and I found this http://img92.imageshack.us/img92/1047/shot0000iy1.jpg

I then asked the player called "mystic" about his GUID, he then did not respond, and disconnected. So we disconnected not wanting to play vs cheaters. I then went to the #aMenti IRC channel. I wanted to get the PB logs + IPS and server logs. So that I could find out who this guid spoofer was. I 1st pmed Winghaven who was help full and did have FTP access to the server but was busy talking to his gf, so I did not want to bother him.

I then pmed aMenti`trix who looked at the logs and told me there was no IP nor any other information on this matter. I asked him to send me the logs so I could take a look, he said that he was playing and would send them to me in the morning (today) I now find my self banned from the #aMenti IRC channel http://img138.imageshack.us/img138/1959/bannedzn2.jpg

I hope this is no reflection onto aMenti because they are nice players. But I do wonder why I was banned just because I wanted to look at the PB logs.
