Unfortunately, it appears that some of the games donated to us for our 24 hour giveaway were purchased fraudulently and may begin to be revoked.
Our 24 hour giveaway for charity was only made possible through generous donations from the community, but it appears some members of the community were less than honest with the gifts they chose to give us. Some seem to have been purchased with stolen credit cards and are beginning to be revoked. I did not think this would be an issue when we started the stream, since I had received many of the games months in advance, but it seems months after the event somebody has finally reported a card stolen and the games are being revoked.
In the event of this happening, please contact serialp0rt or me. We don't have a lot of money and chances are we won't be able to purchase the game for you (it was only through generous donations from many many members of the CS:GO community that we were able to do the giveaway in the first place), but we will do everything in our power to rectify the situation.
I have contacted steam support to see if they will be willing to reinstate the games gifted during the 24 hour stream to the people to whom they were gifted, but we all know what steam support is like. I wouldn't hold my breath about it.
