probably means people who buy stolen cc's on grey markets have potential to use them on cc submit cpa offers therefore all cc cpa offers are suspect.
reality is most people who buy those things go nowhere near cpa networks which require your name, ssn, address to send payment. plus it's been well-known issue for 10+ years, anti-fraud systems are in place. also when they see a high return rate they will freeze your offers and eventually the account. those who this idea appeals to will probably try it anyway. so do it on those $500-$1000 commission cpa and casino offfers not some $30 maxbounty offer.
