It'd be interesting to see what they do if you left a neutral review. (Eg: "Three stars. Cheap build quality but decent for the price I guess").

I suspect they're trying to maintain the illusion they're not paying for positive reviews, just for reviews.

If they're dumb enough to reply back over email that only positive reviews qualify, you could probably forward that to a regulator.
