Great Post. I do agree that those sites have either very bad providers or just scams. They seem to focus on first timers and those that use their wrong head to make decisions. My first mongering experience was with PD, which almost made me quit. She said that the rate she listed was just to "Show Up" to the incall, and it would cost extra to do anything else. It was an aggressive up sell, not cartel level, but it sucked.
Now I only book providers based on reviews from fellow hobbyist. Site like SA, TER, and HX is what I mainly use.
I also had a session with a p-star, and I found it very overrated. Physically, she was built like a real life barbie doll. Rock hard abs, large rock hard breast, and over inflated lips. She had so much work done, i couldn't tell if she was 28 or 48. I am happy I was able to check off "Porn star" from my mongering bucket list, and doubt I will ever try another one.
I think the main thing is if it's too good to be true, then it probably is. Just hope everyone is careful and stays safe. Happy Hobbying!!
