I've been working with over 40 Adult networks and when the pay day came through only 20 have payed me and the rest just closed my account and did not even reply on emails and messengers...
What I learned after is that you have to have a very WH decoy, so if you doing BH on them and they check everything looks very very legit.
I have lost shit lots of money not knowing how they work...
What you need to do it is to identify of what they need.
And what they need is lots of traffic, great referral (like blogs, tgps, banners, etc) and not huge conversion. Before promoting adult sites you must know their conversion rates...
Like some sites have 1:300 and some 1:1500, so you better of, with those that have 1:300.
You probably had very high conversion and thats what triggered their flags on you.
If you like promoting adult stuff that I would say make a plan and do it again, but this time identify the needs of the sponsor you will be promoting and try to furfil them with WH and then run some BH.
This way they will be happy and you will be happy.
Hope this helps.
