I think Noorwegian wants you to change your avatar, as he's said before J-Man.
To just clarify, there are no direct rules against it, so when I was saying it don't take it from me in my capacity as CR. Was just saying that as my personal opinion, it's stupid to take someone else's avatar. Like c'mon, be original. Get your own.
(But if J-Man really wants to use that avatar, there are no rules to stop him unless he actually tries impersonating Fwuffy, which I doubt he'll do.)
