You really like someone's pics and you check her reviews and they are uniformly bad.  But she keeps posting ads and so you regularly get tempted to by someone you know better than to see, but still, you can't help but want what you want.

So she's cute, but 3 out of 4 guys said they should have stayed at home.

There's a good chance, over time, a girl is going to get one or two bad reviews. A bad vibe, the guy is a tough reviewer, an off day.
But consistently bad reviews should tell you something. Do you see a movie or eat a a restaurant with consistently bad reviews? She keeps advertising because she hopes to attract guys who don't have access to the reviews. I only hope if you do see her you write a review.

That's easy.  A score of 2 is clear.  Her performance is horrible, or she's a fraud.  Her pics may be bogus too.

From a girls perspective my girlfriends and i take anything less than 8 as a failure. I have a friend she got a 9 for looks and a 7 for service. And she was upset. She forwarded me the review she did everything with him and i mean everything twice so he was just a hard reviewer.  My lowest is an 8 and that kind of made me feel bad. But when reading reviews why settle for a 5 when you can have an 8, 9 or 10
