Can't give games away?

Are they games that have been given away for free in the past? They tend to be removed from the list of games that can be given

give me one game and i give you one beta the heroes of storm

If you still want to give the games away, you can try in the comments. Just make sure to follow the rules while you do so. If it's a key, it's common practice to make a small puzzle with one or more of the characters to prevent bots from grabbing it before active users.

Funny that posting a link to Rick Astley's "Never Gonna Give You Up" might actually be on topic here.
