What you need to understand is a huge amount of keys were given free and they were revoked because of "being stolen", but they were still given away in a mass giveaway regardless. There's no way to tell what keys were made by purchases or given away free, what I don't think you're understanding is that it doesn't matter on SG. I'm guessing you haven't read the guidelines, doing that might be a good idea especially since you've been on the site for over 2 years. On SG if a game is involved in a mass giveaway the game will be removed from the GA creation list. TBH the game should of been removed from the creation list when IndieGameStand had the massive giveaway(error). I'm guessing that support didn't do this because IndieGameStand had some issues and it appeared to be not functioning. However this was resolved later on and a mass amount of free keys were given out.
