I try a whitelabel with them and get traffic going to it to the tune of about 1.5k or more a day over the course of 9 weeks (3/7 to 5/15).
Here are the results:
I wrote them a few times about why so many refunds. They gave some boilerplate responses. Then they write me back and ask about my traffic to see why there are so many refunds. I give them access to Google Analytics and they check it out and see no error. I leave the account open so they can check my traffic stats any time they want.
Finally more refunds come so I just move the site to another network. Around the same time my earnings (none of which I ever received) go from about $340 down to $135. That is when I move to another network.
At this point I'm pretty angry so I write them a rather aggressive email to explain why my earnings decreased and that I've moved to another network.
I see good sales from the other network that I move to and I write them again and tell them that my traffic was just fine and I accuse them of doing something shady. I ask again to talk to someone higher up to resolve all of this and then they ban my account.
tldr: lots of refunds on whitelabel from bongacash; they ask to see my traffic I oblige; I get sick of refunds move to another network and email them to ask for explanation; they ban me. I was a dick in the emails but that isn't grounds for banning and holding my funds.
