To add to the above, if you don’t have enough funds to “try out the actual subject”, then you can do a few tips below:

If you see a review, good or bad, of a girl then try and search if there are other reviews of the same girl.

Next one - you can also try and see if the reviewer writes other reports of other girls in the past. Do they write positive reviews 100% of the time ? Do they write negative reviews 100% of the time? Do they write exclusively for one shop or operator, or do they have a diverse enough coverage that reduce the likelihood that they are out to attack competitor shops with negative reports, or if they are discount chasing writers who write nothing but good reviews.

Forum tools are available and easy to use for the above. Good luck !
