https://imgur.com/a/ga10oe0I finally got a reply from their support team. They told me the same exact vague list of reasons for the ban and said the decision will not be reviewed :/
I think its just a general copy paste answer to all questions from users whose accounts have been banned.
The support person may also not know the real reason if they answer like that, maybe they will only answer specifically through casinoguru.
Anyway, many casinos still hire and use inexperienced support, so dont be surprised if the answer is like AI.
