I think we'll need to have a verification process on site where you need to demonstrate enough proof of purchase of a product before being able to comment on it. The more of it that you've purchased, the more credibility your claims have.
Here's my proof point - not perfect, but it's something:

It gets more complicated if you're an installer or a reseller, but let's try and keep it simple. First hand users have spent their own $ and that counts.
That gives me 10 Jebao Creditbility Points, 1 Fluval Point and 1 Waveline Point.
