I've had this multiple times.
Tried to leave a big detailed helpful negative review and it gets flagged for being suspicious, with no copy of the review attached so I have to write it all again. And then it gets removed again.
I just looked in my emails. The exact phrasing was "We have reviewed our decisions and concluded that the product you received is authentic. As a result, we removed your review specific to this product. This ensures other customers see reviews that reflect the current shopping experience."
Most recently it happened with a body trimmer, where I never questioned the inauthenticity, and then a zojirushi travel mug that I genuinely believe was a fake, and attached a lot of evidence.
My only education is a super helpful guy from Reddit who taught me the basics of setting up a back end with nodejs and postgres. After that it's just been me, the references and stack overflow.
I have NO education about actual practises and protocol. This was just a tool I made to make my work easier and faster, which I check in and update every few months to make it better.
I just open vscode, run node server.js to get started, and within server.js is a direct link to my database using the SQL above. It works, has worked for a year or two, and I don't know any other way I should be working. Happy to learn though!
(but of course this has set me back so much it would have been quicker not to make the tool at all)
