As far as I know Cloudbet are no longer sponsors of krogothmanhattan raffles. Cloudbet stopped to support it some time ago before these accusations were made. Most of these promotions that you posted away is over and it would be unfair to red tag people who participated in it, because it was long before these scam accusations were made. There are only one active promtion on Bitcointalk -🏆Cloudbet's Cloud 9 Predictor Competition! Free Entry + 0.47 BTC Prize pool! 🏆
https://bitcointalk.org/index.php?topic=5098762.0While Premier League prediction pool isn't organized by Cloudbet, they are just sponsors. Maybe it would be best to remove their name from title.
That was originally "Bitcointalk's English Premier League Football Pool" which was renamed to "Cloudbet's English Premier League Football Pool" later. I don't remember any more how much funds Cloudbet added because I left it long time ago.
I remember correctly they added $500 or £500 to the prize pool.
