I asked myself the same questions when I started...More experienced guys will quickly know the validity of those reviews however, If a provider is caught writing her own reviews or having someone writing those for her, she will be suspended forever.. TER is proactive finding those, it is a really bad business practice and counterproductive to the rest of us who really really work hard for our fair scores.

Paloma is right on..

the mark. An experienced hobbyist can spot "red flag" reviews pretty quickly. There are tons of threads about fake reviews. OTOH, there are also many providers with pages of glowing reviews that are quite legit; yes, we guys can be motivated to ramble in detail about an amazing encounter! Of course, everyone is different.. some reviewers are brief and others write like "Penthouse Letters".

Guys write them to get the free VIP days.  Girls write them to build up their reputation.  If you do your research carefully, and stick to well-reviewed providers, you will be fine.

So many well copy much of what has been written.  That will account for a lot of reviews written the same.  Then there are the fake reviews, by the provider or agency.  In the long run, commonn statements without other indications have no definitve indications if the review is fake or real, just indicate a lack of originality.  Originality, on the other hand, makes for great reading but still does not prove if real or fake.  Of course when it comes to sex, originality really is fantastic.
