That's the problem, and I think it is a legitimate fear.
I wouldn't think I could be blacklisted. But how do I know?
Unlike the very public reviews here, the ladies black-lists sites are designed to be hidden from guys.
And while there are some stable, sane providers - there are a lot MORE crazy, unpredictable, irrational, drug-addicted ones. Most of the world's population is all of these things a lot of the time, but, a job like this - fast money, make-your-own schedule, no "boss" - doesn't tend to attract the most reliable, sensible people. Plus this job is anonymous, which opens it up further to dishonest behavior.
It's the same reason guys who play in the world series of poker can't hold down a regular job. It isn't for lack of intelligence, it is the ability to stick with it and be committed to doing a job, working with others, etc... Sometimes you have to do things you don't want to do that day. You can't just blow it off.
But with this profession, you basically can. It might catch up to you, because of TER and other sites. But that doesn't stop a whole segment of this profession from travelling all the time, posting fake pictures, getting new numbers every week, and just knowing there's always more suckers out there.
