I checked myself on Mr. Number and even though I hire a lot nothing on there for my number. And I have had a few last minute cancellations and have occasionally been blocked on RM by a few guys. So certainly there could have been negaive things about me on there but nothing. This came up with a guy a couple months ago as I told him he was mentioned on here and he was curious about what they said (mostly good things) so he offered to show me what was said about me on Mr. Number which was nothing. 🙂
Don't be too paranoid. I doubt many even pretty regular clients are on there. You probably have to do something pretty bad or have had a weird misunderstanding to be on there.
