I would also like to throw in my 2c.
I personally take the information provided in this forum with a big grain of salt most times. It is true, a lot of the "reviews" on here are blatantly written for an ulterior motive and it is so easy to spot them. These are the ones that have post titles that are meant to attract your attention, and contain details that look OK at first read, but are really ludicrous of you think about it. Stuff like "I pumped her in doggy for 10 minutes, then mish for 9 minutes..." Or a full transcript of the convo with the girl are just bs.
However, even those types of posts are useful in some ways, you just have to know how to use them. Usually the descriptions of the girls are spot on, except for description of facial beauty. For that you just have to get accustomed to the taste of the reviewer. After a few punts, you'll know that a particular reviewer's taste is not the same as yours. So you use that to your advantage in the future.
The other thing is about negative posts. I personally value them more than the positive ones because there is a greater chance that they are truthful. That's not saying they are always right, just that you get the feeling that there is less of a motivation on the receiver to write that review apart from wanting to expose the truth.
