Hi, been doing some research tonight and it seems like the only legit rakeback sites are non-US. It looks like Rakebrain is a scam now (haven't used it in many years), so I'm wondering where to sign up to start fresh with a rakeback affiliate on a new ACR account. Thanks for any help or insight.

I don't understand your statement about non US rakeback sites. Are you confusing sites that offer rakeback with poker rooms offering rakeback?

Many US based sites offer affiliate deals on both US facing and non US facing poker rooms.

You can start by filling out the form at the top of this forum. While it's no guarantee of legitimacy, considering the sites sponsored on 2p2 have to pay out money each month to get their threads, it does mean they aren't inactive busto businesses (and tbh, in my experience the quality of the sites sponsored here is higher than average).

For ACR, you'll be looking for gift/software/video type rewards for signup, as you can't get extra rakeback for signing up with affiliates and this network actually cares about that stuff (so it is policed relatively well).
