I've been given an infraction for something that obviously wasn't checked on.
MinstrelMan wanted a code for a software program, asking somebody to take a look on Demonoid.com as he isn't signed up. So I pm'd him an invite code to said site so he could look for it himself.
All I put in the thread (which has now been expired/ spammed) was "PM Sent"
I get an infraction for it for passing on illegal / copyrighted material by Duckmagic2, even though he didn't know what I had put in the PM.
I note that there have been a few threads where people have either asked for or given out invite codes with no problems!
