well anyway you need to open a topic about their fraud so that people know, maybe some moderator will want to look into your problem
Moderator here don’t moderate scam. Trust system was introduced for a matter like scam and other shady action towards users in the forum.
In your case which is arbitrage betting, this is very hard to meditate since the evidence needs to present privately to trusted user here.
Betby is odds provider and not the casino itself. Once you are marked as arbitrage bettor on other casino that use same odds provider you will most likely branded like that on any casino account that use them.
Exactly there's no moderator here will take action on their problem so better they should not rely on them.
If they have legitimate case then they must post their accusation on right board. But make sure that they bring solid evidence or something that can validate their case.
Since if it happens that the casino also have a proof of their abuse or certain violation made then provably that they would lose on this case. Arbitrage betting is not allow by most of the casino that's why its important to read the rules before taking action to avoid getting issue with them.
