That's probably the harshest way to reply to OP, so I'll take it down a notch and just say that OP might just be taking out his frustrations--whether it's his own gambling problem, losses, whatever--on Rollbit, when it might not be their fault entirely for not closing all of his accounts.

Even if they didn't, OP ought to have un-bookmarked that site, erased whatever traces were left from it from his phone, PC, you name it and then shouldn't have tried to log on again.  On top of that, there's nothing I can see that would prevent him from creating an account on another gambling site if he decided to indulge his addiction against his better judgement.

In other words, this really isn't a scam accusation, just a complaint without much basis.  I understand how problem gambling can wreck lives, OP.  I sincerely hope you can get your life back on track if you've suffered any of the consequences of it--and if not, I hope you never learn how bad it can get.
