[suggestion] A way to make sure people activate games they won

This site keeps tabs on all the games everyone wins, it also keeps tabs on all the games in everyone's library.

Could you make it so that after a game has been won and the winner signs off a game as received, the next time the user logs on a resync is forced to check if said game is in the winners library. If not, they are prohibited from entering further giveaways until it is.

I can see a potential flaw with a winner not claiming the gift received and the gifter claiming it's been sent (I don't know how these situations are dealt with currently). Perhaps the prohibition of entering giveaways can be triggered after 3 won games are not in the library. That way there is some grace for mistakes, but when you get to a certain point it starts to become really fishy.
