yeah its all about combating fraudulent signups. I personally don't stress over payment delays as I only promote programs that I trust will be there in the long run.

NO I will not touch any of the BF Bucks or other Media Revenue programs. Burn me once, shame on you; burn me twice, shame on me. And how many times have SOBV / DeeCash / Media Revenue burned webmasters by first not paying, then dropping all accounts (thus keeping rebills for themselves on any revshare accounts), then making special deals with select webmasters (only to stop those deals days later without notifying anyone), then having T&C stating they only pay on primary billers (even though they purposely pushed affiliate signups to secondary processors), and of course having sites filled with illegal, unpaid for content (stolen from reputable companies like zbuckz).

Really, its up to you to decide if a program is reputable and trustworthy enough to promote it.
