Yes, I have. I actually joined an escort site once. The site only took bitcoin for payment, which I didn't have. The next night I had over 50 text messages and 100 plus emails from guys requesting dates. The site had given me a free 7 day trial! My cell number was posted on my profile. I had listed 100 an hour in call and 150 an hour outcall! I chickened out because I was afraid to get arrested.
