I too was contacted by Betnomi via PM with the same message as I had supported the flag but didn't leave negative feedback. I also participated in their review campaign and think that they are sketchy. This was my review -
I didn't get a reply from them at that time. In provably fair games, users are to be provided with the seed hash prior to the game to prove that the results aren't predetermined or manipulated. In the case of Betnomi, they give you server seed but not the output hash. The result is generated by merging the server seed with the first three clients' seeds. Even if you are one of the first client seed, in no way you can know the other two client seed provided are not manipulative figures.
I still believe they are sketchy and would not remove my support unless they come clean about the fake team and about how the game works.
Review: Tried the blast game several times likely 100 rounds on Mobile and Desktop collectively only to go bust at the end 
So I'm not able to check if I could withdraw the funds without any hassle. The game experience was fine, no issues faced even in times of slow internet connection it worked smooth. Checked for the provable fairness, it worked fine as supposed. But I don't like the way probably fair works.
Do correct me if I am wrong.

When the round begins, the game logic merges the server seed with the first three clients' seeds. As a result, a new number is generated via SHA512 hashing algorithm, which represents the game result.
Why the need for three client seeds? How can I be sure that you are not manipulating the client seeds?Do correct me if I am wrong.
