For sure, the other typical 'long reviewers' are the 'Vine hopefuls'. People trying to build a reputation for good / helpful reviews so they can get 'free stuff' from the Vine program (where Amazon sends you products, ostensibly 'on (indefinite) loan') to review.
They're yours to keep, although they reserve the right to ask you to send them back within 6 months (never happened with me). You can't give them away (you're expected to dispose/recycle them) and you're not allowed to post reviews of those products in other places, although I've seen that happen.
