lantimilan please stop talking BS. Non-steam is not supported here. If he has problems with his illegal server he is on his own.
If you, or also him, decides to remove the most important part of the STEAM_ID, namely that it is unique stop crying about it.
Make your server steam-only and all of these problems are gone. A REAL steam-id cannot be faked, stolen, copied, whatever.
