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 mediate 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.
OP can just go to CasinoGuru or AskGamblers for that matter, where the evidence from both sides would be seen.
