I've noticed something with your reviewing on the PFF, and I couldn't help but step in to make one tiny comment:
If you don't explain why certain mistakes are mistakes (or generally bad) and how to fix them, then the writer won't be able to get anything out of your review because by the end of it, they still don't know how to avoid the mistake in the future or why certain things are bad, so they'll just end up making the same mistakes all over again because they don't know what they're doing wrong. That and you end up looking like a snarky jerk, which you generally don't want to do in a review because then the writer will be less likely to pay attention to you.
So, for example, rather than tell someone that writing in the reply box is bad, tell them why it's bad and point out the advantages of writing in a word processor instead. They'll be able to learn from that kind of review because you're patient enough to explain things to them thoroughly, rather than just point out their flaws in a biting or condescending manner.
