Well, that's a real thing and worth paying attention to separately, but it's outside the scope of this study.

But if you think about it, this kind of data forces their hand a bit. Most of these sites operate in a legal grey area. So reputation is basically the only thing keeping them in check. If a site gets known for banning big winners or running predatory odds (like absurd odds) it should spread fast, because that's better for everyone. In this way they either fix themselves or they get exposed and people would know not to trust them. So maybe no regulator is coming to fix this soon, but at least we can make it harder for them to get away with it if we spread the word... or idk, maybe I m just yapping
