There are other industries that I would be worried about, like the porn industry (also unregulated), but mainly this one, and mainly because I have first hand knowledge of sh-t that goes on.
Also, eCogra is garbage. Before this year they simply were an organization that allowed only Microgaming branded casinos into their list and most likely were paid a large sum of money to do so. I doubt they denied membership or had any problems with any casinos unless a problem became public and they had no choice but to make a stand in order to save face.
