All I found is that the withdrawals takes a lot of time, bout 14-20 days
This alone is already more than enough reason to boycott that bookmaker, what would anyone want with a casino that let's your withdrawal request sit there for 14 to 20 days before processing it, such a casino is a timed bomb waiting to blow up, and sooner or later, they would stop paying entirely...
I am curious as to what else yoh want to know about mrSloty if withdrawals take such a long time.
a lot of bad things about the reviews site were made by competitors to drop them, so again, maybe the review was made by a cheater who found out to claim a bonus, so we don't know because we are just guessing and reading data from the review site where sometime received payment from competitor (like abel1337 said).
and also, Mrsloty is a sportsbook where lots of cheaters to earning money, we are not surprised right?, because who's have been a long time here know what happens on any sportsbook in the past.
so I don't want to rush to verdict the site is a scam or not, I have to wait for paxaman to explain the detail of why the withdrawals take a lot of time, maybe he was multi-account and the team found out he was registered using the same of multi IP.
