blackhat traffic not cutting it anymore

all my traffic's been blackhat since I started. nothing white. my epc's dropped too low to tolerate at this point. will adding in quality whitehat traffic get my epc back up? is ppc, email good for this? btw im using email submits. i know a lot of people talk about email subs converting well day 1-2 then dropping, which is exactly what i normally experience with my all blackhat traffic; however they claim they're doing whitehat - is this really true?

It's your decision to make, I believe nobody advised you to go black hat and short term when the options are there.

thank you Captain Hindsight

what is whitehat?
