Epinions has been one of the oldest sites that rewards its member for the reviews they write on its site. Remember amazon also has the same things but the review writers do not get paid there. The reviews are rated by peers and other members so there is a check and balance.
Epinions is doing away with the check processing that it had followed so far. Instead, the payment is being made via paypal. Members must have paypal account to get paid. Here is what the email sent to members say.
The January 10, 2013 will be the last day of redemption process by check. All future payouts will be automatically distributed to you by PayPal starting January 15, 2013.
