Deleted

You can hide the game on steam and never see it again, if you don't actively search for it.

I think we've all been there but the solution you propose might create a problem with people giving away games they won to gain CV, thus removing the issue of needing to have their wins activated.

You can contact the creator and ask them to delete the giveway. You'd probably want to work something out, like give them a key for the same game or one of similar value. Then post a comment in the GA saying you agree to delete it, and have them create a support ticket to remove.

Just mark the games as hidden in your library, that would work a lot easier lol.
