[cod] COD2 GUID = 0 exploit

[luke at techfreak.org]

Yeah, it's likely two (or more) issues. If the master server is returning
faulty values you will usually see at least several players on each server
with a guid of zero.

If you just have one player with a guid of zero it is likely hes using
some exploit or hack.
