It seems ridiculous to trust those who just joined the forum with a new account and have them happily create threads saying bad things about the casino.
I think they are just accounts owned by certain people with the aim of being able to drop the good reputation that some casinos have.
This kind of account should only give bad statements to the casino, be restricted again because they only say bad things without any evidence or details that can really be trusted.
We can also see that in the threads they made there were only prolonged debates and debates.
