Or are you talking about when someone impersonates himself to be something other than he actually is? Like a normal user saying he is a moderator? Something like that?! That too is not done of course... AND could get someone into trouble pretty easily. =)
Otherwise I'm just as lost about your subject as Salvidian is... =/
what i think he's asking is if you can copyright a game mod of sorts. like a minecraft mod.
Still doesn't make any sense to me... I could be sounding like a noob by stating this, but... mod as in =moderator, or as in =modification, or as in =mode?! What is it that he is talking about remains (more than) a little vague here guys... (O.o)
