Dave, sorry but I have to disagree there, I don't see how pointing out that someone who is clearly using a cracked version is not going to get a great deal of help here, or this is in anyway going to harm or even boost multi player numbers.
I would hazard a guess there is a fairly active cracked scene given the percentage of them make it on here looking for help, now if a few of them actually went out and bought a licence then things might start changing but whilst the cracked community is allowed to carry on they will.
