ARTEZA Canvas Boards for Painting

My previous review of this product was declined. I was advised today via a "no reply"email from Amazon Reviews. I can only surmise that the person who made the determination that my review could not be posted on the Amazon website has no idea what paint pouring is. My intent was to warn fellow "pourers" that this product is not appropriate for the technique. Paint pouring is a method by which copious amounts of paint are actually poured onto a surface, then tilted off to leave the desired effect on the surface...in this case, a canvas board. During this process, the paint being tilted off will seep under and onto the back of the canvas. As a result, with this specific product, the adhesion between the canvas wrapped to the back and the backing holding it in place becomes compromised. The canvas will then shrink as it dries, ruining the front of the painting. I have little doubt that the product will perform as intended for "light painting" on the front of the canvas...I couldn't attest to that, since I've only used it for pouring techniques, but gave it a 3 anyway. I was trying to warn other people who "pour" that this product is not right for that process. I was neither rude nor profane. I am a very frequent customer of Amazon and, up until now have read reviews to assist me in my buying choices. Can I not trust the review process?
