I've just received an email asking for a review on Trustpilot.
I am not so sure if this is a good thing.
Some players might write bad reviews if they lose money.
Although this would not be a reason for a bad rating....
The team may not be alert enough to the opposite effect. Your guess is correct that even if a player loses money in gambling, he can get rid of his anger by giving the platform a bad rating. If so, it could create a bad situation for the platform.
So I think the team of this platform will take the right action, so as not to create a bad situation for their platform.
