Meh comments aren't an issue, a quarter of the people on moddb have the IQ of a pencil anyway... Moddb needs some kind of order to say that this is wrong, if the staff are too pressed to do it perhaps something is needed to show the community that you can't just put whatever you like in a mod or take someone else's work and claim it as your own. One day something like what happened on HIT where a developer threatened legal action against the host because of illegally ported models, I can see it coming...
[edit]That Modern warfare CS mod has been released apparently, but there's no download link, perhaps the admins will realise everything is stolen from retail and delete it...
