Out of 56 completed transactions during the study, only seven of the team's orders failed to arrive.Though top rated credit cards already offer significant consumer protection, few customers feel compelled to file transaction disputes after packages arrive from fulfillment centers in India, China, and even the United States.Visa, MasterCard could team up to block spam fundingEfforts by the technical community to block consumers' access to potentially fraudulent websites have often been thwarted by a combination of hacker attacks and customer frustration. The researchers suggest that American credit card issuers could help curb the growth of spam-sending botnets by choking off the supply of cash to merchants on a "financial blacklist."The team suggested that a partnership between credit card platform providers like Visa and MasterCard could eliminate many spammers' financial incentives, just as a similar enforcement action closed off most Americans' access to illegal online gambling operation
