This has to be the most idiotic thing argued about. Personally i think people using renders from games or wherever they come from without permission isn't really bad at all. Some of you are using ripping sigs as examples which is a totally different situation then using a character that somebody might enjoy. One thing about permissions to use a copyrighted material/image in your sig isn't against any law unless you are using it for profit or the creator has specifically said not to use any image without permission. Companies won't lose business because some fan decided to make a crappy sig, are you an idiot?
