Banned 'League of Legends' Players Sent Creepy Surveys

First off, I would like to know where Riot gains its consent to store this type of Data from its users.

Second, it is already a botched study do the fact that is forced on the player, unless they want to forgo playing again on that account. You honestly expect these results to be an accurate representation?

Third, what about underage players? To my knowledge this isn't on the most legal grounds to perform with out the parents consent.
