Especially if she has your contact info.
Some guys will call me a pussy and a mangina for saying that, but in the end, this is about YOU. You don't owe anyone else anything, and if you pay for VIP, then you REALLY don't owe anyone anything. You paid for the session with your hard-earned money, and you pay for VIP, so what do you get out of some guys who are telling you to write a review? The old "thanks a lot, buddy"?
If you did your research and her face was just not up to snuff (and her face pics were blocked), that's on you. Sorry, but this shit happens from time to time, and that's not her fault. If the pics were real, but she blurred her face, and you relied on the reviews of the other guys to make your decision but were unhappy with how she looked, that's not her problem.
However, if she stretched out or airbrushed the pics in some way to completely misrepresent her figure or body, that's entirely different.
Practically speaking, if she has your info and she is unhappy with the review, she could trash you and disclose that info on a blacklist. Again, PRACTICALLY speaking, that's a hefty price to pay for the fact that you hooked up your "bros" (and I use that term very broadly because these jackholes certainly didn't pay for the session or even for your VIP).
If a guy reads this and wants to know who to avoid, he can PM you. That is, unless he doesn't pay for VIP, and therefore can't PM you, in which case he's a cheapskate looking for someone else to do the work while he gets the spoils.
Bottom line? This can be handled via PM and the backchannels as opposed to publicly destroying her. And like I said, if she wasn't what you expected and this was purely in the face, that's on you, not her.
I saw a girl in Miami who was rated mostly 9s and 10s, and she was downright ugly in the face. But I didn't write a review, because that's entirely my fault. She blurred her face, but that body was sick, and it was hers. Ultimately, I wish I had spent the $500+ elsewhere, but if I trashed her in a review because I was disappointed in her face, that would be laughable.
My two cents.
