Cute idea, in prospect, but really bad in practice. If people could upload their own, what would stop them from just uploading a 10,000 AP armatar, or uploading some obscene stuff? Also, we wouldn't get any new armatars if we did this, because maybe a tenth of the people would use them. Besides, you've barely unlocked a fraction of them, and they just get better.
Yeah, that would be cool. But some people would probably use explicit inapropriate pictures. It would be better if AG made a system where you send them the url and they approve it before you use it. That way nothing bad happens.
I believe one of the main reason most of the members stay around here is because they look forward to seeing the new armatars. Allow them to upload pictures and there would be many more inactive members.
Yea, people could upload obscene pictures or they could just copy and upload a 10,000 AP armatar. Besides, the armatars are cool and you haven't even unlocked one tenth of them. They get better.
