If I am not wrong, are you talking about richardo3o and his alts? I found this was claimed that duckdice has offered him $5 for each Trust pilot 5-star review. Here is the archived post https://ninjastic.space/post/59081569. This guy wrote 88 posts in this forum 85 of them about duckdice. Surprisingly he deleted all his posts after he get the lossback or cashback.

I don't believe a casino will offer $5 for the Trust Pilot review. If they do, they won't mess up with the payment. Because they know it's unethical and if they mess up with the payment. They may expose them to the public. So, Why would a casino pay for reviews and later deny to pay while they know they will get exposed? It was a Good try OP. You fooled everyone. Happy April Fools
