Ignore giveaways for certain games

There is, click the eye icon next to the game

Great that you found all :o)

I want to advice you a minimum level for public GA's.
That lower the ammount of autojoiners, users that break the rules and users that won 300 games and gave nothing to the site.
In the end a lower ammount of work after the GA ended and each one can be reach level 1 with ONE giveaway for a not free game (to give 1 cent is enough). And none that have a account for 100$ isn't so poor that he can't give a cent.

If you don't know it, you can and should check your winners with sgtools.
