It means her service is top notch!!
And thus many hobbyists tend to gravitate towards that particular provider.

BTW, just a few questions:
1. how many is 'too' many?
2. what's your definition of a slut??

Strange question given that there are no angels here, provider or hobbyist.  If you are looking for a good girl, go to a convent, you will have a better chance of finding one.
    A lot of reviews means that she made hobbyists want to sing to the world afterward.

I'm not sure.  If you misspell four words out of sixteen, does that mean you're a moron?

The real question I think he happens to be asking is that if she has seen many people, perhaps his needle thin dick might not be big enough to even come close to fill the woman up at all because in his mind somehow the number of people she has seen affects the tightness of her.  Of course we all know that this does not happen.

Of course he spelled everything correctly, just used the incorrect words.

Excellent question ..........

I wouldn't use the term "slut" ...and she may not be loose ... however, if she does have a ton of reviews in a month that does raise a very good question as to how many sessions she schedules per day .... One has to wonder if she has a ton of reviews in a month how many more did she see that didn't post a review ... I know of one lady who sees up to 6 or 7 guys in a day .. I just don't think I want to be the caboose on that train. Usually a lady with many reviews is just popular and good ...
