once again i'm gonna make the party crasher here, although i wouldn't mind any king of recognition existing, a lot of MMO player would do anything to get all titles available including posting fake or stolen addon and/or promoting them everywhere if it came to a number of downloaded criterium to get the title.

Once again, people most rewarded will be the best PR, and everyone else will lose from it. Users, authors and ESOUI moderators.

I don't know how you intend to control that, but it won't be easy to be fair to everyone.
