Why not take the money and just not remove the review?
As of this moment, I can say that I've never received a penny for writing a review. I have a small number of Amazon affiliate links on my website, but they're all for products that I personally researched, bought at the advertised price, and now recommend. No one can credibly accuse me of conflict of interest. If I say I like a thing, it's because I genuinely like it.
Getting a few bucks from a scammer isn't worth the reputational risk to me.
