As of 3/21/2023, any Amazon product opened in a new tab comes up with the warning, "The page isn’t redirecting properly". This may be because of affiliate links that are no longer good.

Interesting idea, however the use of the simple regexp terms is simply not accurate enough—in my experience of testing it, it only blocked legitimate reviews, mostly because they mentioned that some _other_ reviews were sponsored.
Also, this extension automatically replaces your amazon links with affiliate ones so the creator gets a kickback (it can be disabled with a checkbox in the options, but it's disguised).
Another thing is that, I'm not sure exactly if it's behaving 'correctly' (as Webber intends), but I've found a review that is hidden when 'aggressive' is enabled and not when it is disabled, even when it definitely doesn't match anything in the aggressive box (I replaced it with one random string of letters to test). Now, maybe it's filtering it for another reason? It seems fairly legitimate to me.
Also, when I removed everything from the aggressive box, with aggressive mode still enabled, it hid all reviews (not a major bug, but still).

fake extension, injects amazon affiliate links into everything you view, supporting the creator maliciously

Please add smile.amazon.com /.de /.co.uk etc!

Works great! A very helpful add-on.
