Since you didn't add strong evidence, take this as a warning and consider doing deeper research to see if what you posted is likely to happen. If you have any other proofs you can add here, why they blocked you and what kind of conversation they had with you, because if they blocked you from their social media for no reason, then their motives must be doubted.
I don't understand why you are talking about social medias and why you claim he has been blocked by them. He had talked about this case elsewhere or post from him here has been deleted? If it's because of another conversation you should quote his post or a link towards it.
Anyway, it would be better if OP could post a link towards a paying version of the game and some screenshots. But I didn't find how to check the provably fairness of the rounds in the demo version(free) of the game in his link, Indeed.
I actually tried reaching out to them on their social media platforms but they ignored and deleted my comments on LinkedIn and blocked me on Facebook.
There's no way how to check provablyfairness on paying versions too check them out on
https://wolf.bet/ or
https://sportsbet.io/casino or any other popular casino.
Their official provably fair page
https://spribe.co/provably-fair doesn't provide any mathematical methods or script to verify their games either.
