1. None yet with the gambling site that I mostly use. But for other online gambling sites that I tried which accepts our local currency, I don't like how their RTP works. Sometimes their slot games go way far before the RTP clicks in which makes you think that something fishy is going on. As a gambler who play casino games, that's the only thing you can rely on when you are on a losing streak and how I wish they could make it at a shorter span of time before it kicks in.

2. I don't think there's a way to solve that problem. I could make a report about it but I doubt they will change that since it is the reason for their games to keep on going. Business is business, all we can do is avoid them if we feel like they are not even trying to give a fair RTP.
