What is the best way to promote gambling/bingo CPA?

I have tried to use Bing ads to no avail. They say on live chat and on their editorial guidelines that promoting gambiling/bing sites are forbidden. Yet when you search gambling/bingo on their site you get big companies publishing their ads on bing.


I have also tried facebook and my ad got rejected.

The offer targets UK individuals and is an email submit offer. So basically people enter their name and email and sent to a list of bingo sites they can join.

So are there any other alternatives to promoting this type of niche? PPV is my last resort as I am not so comfortable dumping $1000 in leadimpact or the other networks out there.
