[Suggestion] Contributor "Excluded Games" list

For contributor giveaways, I have a suggestion to make them work a little better and stop people from breaking the rules to get join them. Yes I know, report the giveaway breaking the rules and it'll be removed but they still slip by.

Option 1: SteamGift stores a database of "Bundled/Exploitable" games which is updated with games that appeared in bundles, or exploitable.

Option 2: Allow users to create and maintain their own lists of games they don't want counted into the total for their giveaways.

When someone creates a contributor giveaway, give them a checkbox that allows them to exclude giveaways that were created for these games. IE: User has $200 in giveaways, but $75 of that are from games that were in indie bundles. Therefore if they try to enter the giveaway that requires to have contributed $150 in games (and this option selected), they won't be able to.

Yes, there would be valid giveaways of games that were done before they appeared in bundles, perhaps also add a date field in the list that will ignore giveaways for that game after that date.
