yeah it's the same with gambling and poker. In these worlds if you slip up you probably won't be given another chance, and once you lose your reputation, you have nothing left. Nobody wants to deal with you anymore. Sure gamblers are no angels, but to be honest, I have found that online poker players, especially at high stakes, are much more ethical and considerate of other people than a lot of the other people I see. The fact that they are constantly under scrutiny from their peers and the rest of society probably makes them think a lot more about what's ethical and what's not ethical.
So, paradoxically when you are part of a negatively connotated industry, there is a good chance you're actually much more ethical than the vast majority of other people.
