There's no scam accusation here, I bet the OP is just warning us in terms of the change of the algo of their game. The change of probably fair into none is too suspicious without them announcing it if its "true". Although i won't agree just yet when there's no proof shown like the chat logs, the result when using the probably fair verifier using the seed (server/client), hash, etc. from Spribe itself.
Let us say the OP has not created any scam accusations and trying to make us aware of the site to avoid our loss. If so the post should be created on the reputation section instead of the scam accusation board.
Well i think it belongs there too as well as here too because if you think about it every bet made on their games which aren't provablyfair but claim theyre provablyfair qualifies as a scam
