Don't worry, it's not your fault (And hey, I think it's a silly rule too, not being able to use a character creator etc). I can't understand why they're prohibited; they're simply a way for those who do not draw (or cannot draw) to create references of their characters.

Plus, I doubt anyone takes the time to read the AUP anyways. I only found out about that prohibition because it was announced in an update I randomly read a few months ago.

The icon should be fine though, I doubt the moderators will get ticked off over something like that.

I guess it counts as using someone else's "art" in a sense. something like that maybe

But hey, thanks for telling me though
