I guess even though CPA lead conversion is very very less.Most of the days on the posts where I put cpa lead javascript,I'm only getting maximum 10$ per day.But one thing good about it is they never ever shaves leads whereas Adscend Media etc shaves leads like hell.Also wont I get banned from different CPA N/Ws if I use BHCB.I never tried it.I am sometimes getting close to 3000 clicks on cpa lead surveys and the conversions are really really low.
