Yeah. This is really worth doing if you know the subject matter well or how to solve problems with the casino. Or you have a lot of experience and you immediately understand the purpose of advertising texts disguised as reviews.
And in any case, it is worth fighting disinformation; this is the right and useful activity for any person. And if we talk about gambling players, then exposing false information sometimes allows other players to avoid many mistakes and, ultimately, save their money.
But not all problems at a casino will be found unless the gambler has gambled at that casino, so gamblers will review the casino they choose to gamble at and they generally don't know the problems at all casinos unless they check in detail at each casino to ensure the casino system is fair and does not complicate the withdrawal process. However, I agree that if they share an explanation of their experiences at each casino it can help others analyze to test the suitability of the casino, and if they share important information from finding indications of a scam casino then they have saved other people's money from scammer activity.
