Well, scammers are very rampant in the internet so if newbies will be easily lured by those tempting offers, expect that all those offers which are too good to be true will certainly turned into scams. That is the reason why we need regulated gambling casinos to lessen the scamming incidents, and to maximize reputable casinos in the market. And by having provable fair system, having rigged games are discouraged so as to give fair games to all.
Even with regulation or not, scammers will always be a part of any industry, especially in the gambling industry.
To minimize the number of scam incidents, the precaution should always be to start with the user itself.
Newbies are not dumb enough to fall easily on those tempting offers but unfortunately, not all newbies are like that and many failed on that part.
The issue is that casinos can open their business freely on the Internet whenever they please. There is no regulation they could be forced to adhere to. If they conduct their business without scamming the users, casinos that are not prone to all those KYC regulations are what many people are looking for. But no KYC casinos often come at the cost that if a user gets scammed, going for recourse might turn out to be cumbersome to say the least. Most likely it is impossible unless it is a major casino that has a reputation to lose and that is somehow registered and licensed. Sticking with the big names in the industry that have a long history of trustworthy gambling is the best choice here.
