It's pretty random on their part how they do it, imo, but at least some get what they want.
I hope for everybody to get their chunks they've got there eventually, but I doubt it looking at where it's going..
Perhaps they are choosing small withdrawals over larger withdrawals or some sort of selective approval to save some bankroll. Those user that successfully withdraw will surely go here and will update us about their success that create again a chain of false hope while others still have problem.
Typical behavior of scammer/shady casino that still wants to milk some more to other players while giving some small payout to attract more players to deposit.
