While I get that those groups exist, the sellers didn't have to do any new work to "convert" their existing reviewers.
Most if not all of the top-ranked incentivized reviewers already had longstanding communications with sellers via email.

If you have a Facebook account, you can find those groups easily. Though you may have to search for obfuscations like "AZON".
