I am not judging their cases (whatever it is) with Bitlucy with above but it seems these users always had issues with casinos. It seems eventually they fall into problem with casinos. With Bitlucy may be this is just a continuation. I have only skimmed the first pages of their post history. It was just a quick one.
I don't think this is correct that you dig those gamblers with their own experiences on other casinos, I understand it's odds when a gambler faced so many problem in other casinos, but the gamblers I mentioned above isn't a trolls who trying to hurt the casino reputation. Based on the list you provided, they're correct with their accusation especially they have provide an evidence.
He give an evidence where Betfury cancelled his bet and returned his deposit amount, then he said he have a similar situation on June, it was a mistake by Betfury and Betfury pay his winning.
TheSuspect500 aka CSGO500 team admitted he was wrong, so he pay all the winning with small compensation.
AceDBets is a scam casino since they got negative feedback and BETOP.GG always have slow withdrawal problem, it's make sense he have a bad experience.
I can't comment to much about this accusations because there's no more explanation about bad bet attempts, it's either mojdragane is an abuser or rollbit wrong suspecting a player.
When someone takes unfair advantages and when they get caught, when they fail then their only weapon is to hit your reputation.
When good users are getting paid in a casino they do not care much and come to public to post about it all the time.
I understood, but usually an abuser is spread a completely nonsense and trying to hurt someone reputation while the good users sometime didn't do that. Though it's just a personality and we can't use that to trust someone since many people are an professional actor, but since most of the reasons I see regarding this withdrawal problem are because of abusers that taking advantages over your casino e.g. bonus, promotions, features etc. I think it's better for you to make your casino more strict, though you may lose some gamblers, but this can be an option (it's good you have removed the free bet and have a hard requirement of the welcome bonus).
The strict rules what I mean is:
-Ask a verification through his phone number when sign up
-Ask a KYC when you in doubt to prove he's a one person or have other alts.
-Tightening the wager requirements in order to prevent someone withdraw his initial deposit.
