TER simply doesn't have enough people to catch every fake review out there. Of course, there's a small possibility it's not fake, and maybe just a coincidence. I've reported more then one person to TER in the past on suspicion of fake reviews.
That includes one person who was dumb enough to copy one of my reviews, a distinct no-no! If you are going to be stupid enough to write a fake, at least make it your own. Don't just blatantly, and obviously, copy someone else. At best, it will cost you credibility, at worst, it may get you banned.
Don't be cheap. If you want VIP, earn it with respect. Buy it, or write legitimate reviews. I started out writing reviews as a way to go back and relive the experience. Especially if it was a visiting provider, who returns much later, I'll have a way of knowing if I want to see her again.
Somewhere along the way, my reviews have begun to earn respect. In all my reviews, not one is a fake, and I would never dream of writing a fake as I would not want to risk damaging my credibility. I also enjoy helping my fellow TER members when I can. I've taken and given advice in the past, and hope to continue to do so for a long time to come.
