Amazon is complicit. When I've left I review about cards offering money for reviews packaged with an item I've ordered, Amazon has deleted my review.

When I've followed up, they told me it's actually against the rules to call sellers out for this behavior - your reviews can't mention "promotional materials", even if they came IN THE BOX of what you purchase.

Disgusting. Should be a case for the FTC (or equivalent agency in your country). Also, competitors should sue Amazon for such anti-competitive behavior.
