Nihil, the CD key of the game battlefield has been hashed (I guess encrypted). Here's one of them:

No illegal or unicode characters IMHO....i dont know much about encryptions.

CDKey Hash: 85a2a4c5430e658b43eacb93f3d83dc6

While coppying and pasting this...perhaps..... 8524-5430-6584-3933-836....Nah

Counter-strike is a standalone mod which you need to purchase today to get the appropriate CD key.
Any information we could find...would be great. We do have admin and they connected onto our server, which is how we got the cd key hashes. One of the other members was able to get them. We also have their IP adresses which we're banning.

Teamwarfare should have received the letter by now and taking care of the sittuation.(Dont know if one of the other members sent the letter yet)
