I am afraid that no one can really respond to this!
That is what is said on the site.
We are simply told that the company has been involved with 2 private groups and paid out before.
Unfortunately no one can verify this since no one who has been paid will venture forth to claim this.
Remember that everyone who has been part of any of those 2 groups would have signed nda's that would prevent them from shouting this out!
Sorry but that is the best I can say!
Best regards
