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 hère 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 thé game and some screenshots. But I didn't find how to check the provably fairness of the rounds in the demo version(free) of thé game in his link, Indeed.
