Base on my observation as an old time user here in the forum. Scam casino usually don’t invest much on license and promotion here and social that’s why they are easy to spot now compared before that most of the casino even trusted don’t prioritize license since most of the games being offered way back then was just a probably fair game like dice. But now even newbie players can easily spot them and just go to the trusted casino which always active in promotion here.
Plus when you have places doing millions of dollars worth of promotions, it is a lot easier to see who is a scam, which scammer would spend millions when they know that they can't just get that back, or they can simply just take whatever they can normally and do not worry about the rest?
I understand that it is not going to be easy, but it is going to be pretty easy for many people who are veterans, only hard for the newbies. I haven't been scammed by a single casino so far, not because I am smart or anything, I am probably not matter than any of you, but I have been here and it is so clear, and I guarantee you if people spend time here, all of them will learn to avoid scams.
