If you want to throw a party, poker rake back programs may help you raise some cash. However on some sites, rake back memberships may cost you your winnings.
A rake back deal means you get part of your rake back from an online poker room.  Rakeback deals are administered by third party affiliates. Not all poker rooms allow their affiliates to offer this incentive. Some do it anyway. If you sign up with one of these you run the risk of losing your account and any winnings you may have accumulated.
The best way to tell if getting rakeback is okay at an online casino is to read the terms and policies before you sign up. Most online poker sites will not allow you to sign up with a rakeback affiliate if you have already registered with the casino. A few will let you create a new account, check first!

Rakeback is used only in online casinos because of the difficulty in tracking members’ earnings. Casinos in the real world offer comps and other bonuses. These are actually rewards for being a loyal customer as well as spending a lot of money.
Two of the most popular types of rakeback programs offered are the flat rakeback where you get the same rakeback percentages regardless of how much you have paid, and the progressive rakeback where your percentage depends upon how much you have paid.

On some online sites like Party Poker, rake back is not an option. Instead they offer bonuses and other incentives. If there is a link to Party Poker, rake back is not available and the affiliate offering it is being dishonest. Do not jeopardize your hard earned cash by signing up with this affiliate. Odds are there are a hundred other fish in the sea that won’t get you thrown out.
