So I've been using both for some time now and never had any problems with affiliates. I know they both have that disclaimer ("don't accept affiliates you don't know!") though I accepted numerous affiliates I didn't know.
When using WarriorPlus, I DID check the affiliates background slightly prior to acceptance. I wasn't willing to accept them if they had 0 posts on the Warriorforum unless their note made sense and was legitimate.
Well, I woke up yesterday with 4 or 5 PayPal chargebacks and they all came from the same affiliate. I've NEVER been asked for a refund out of hundreds of sales. Clearly something was up.
Then I started receiving emails from these people letting me know they had no idea who I was... that they didn't purchase anything from me... and would like a refund ASAP.
Moral of the story is... don't accept affiliates you don't know (unless they have SOME sort of reputation to base their legitimacy on). This affiliate must have gotten access to other people's PayPal accounts. Not good.
Only a small headache caused from this matter, but if expanded to 100+ sales and then 100+ refunds, I can't imagine.
Just a piece of advice going forward. I know I'll be using it.
