Just sharing my observations. IMO the FB report button is often used to silence legitimate critics.
As someone who cared for my family’s ecommerce efforts, and having been targeted by fake reviews by competitors on Amazon, my concern is that type of abuse. Probably not something of concern for your project at this stage. Perhaps down the road if you achieve good traction, which I wish you well in achieving. Sorry if my feedback sounds very critical, perhaps you can relate, I map out problem spaces to help me make solutions.
