Although most investigators and credit card fraud teams focus on minimizing cybercrime and identity theft activities launched through spam attacks, the California teams discovered a network of businesses that developed complex fulfillment systems to prevent chargebacks and to encourage repeat business.Under this model, a team of spammers could make more money over time selling many of the same goods to repeat customers than by simply selling credit card account details to fraud rings. 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 operationd that investigation resulted in 74 people being detained in 56 cases that were handed to police for possible prosecution. Lead poisoning can damage the nervous, muscular and reproductive systems. Children are particularly at risk. The poisonings in Taizhou were among many in Zhejiang, a major battery production center, and elsewhere in eastern and southern China that appear to have prompted the latest push for better local enforcement of laxly observed environmental standards. "All remediation will be conducted according to strict discipline. Dismantling of illegal smelters and small, unauthorized electroplating workshops will be conducted strictly according to law," the statement cited Cai Xumin, a local official in charge of the Taizhou cleanup, as saying. In Zhejiang's Deqing county, where 53 people were hospitalized after tests in late April found high lead levels in the blood of 332 residents near a factory making lead-acid motorcycle batteries, all three local factories were ordered to stop production, said county public outreach official Ji Huibin. The crackdown is aimed at preventing and reducing contamination of the environment with toxins such as lead, cadmium, mercury, chromium and other heavy metals that have left much of China dangerously polluted. Thousands of children were affected by lead poisoning in several provinces in 2009 and 2010 because they lived near metal smelters or battery factories. Combined with scandals over contaminated foods and milk, the issue has taken on urgency for government leaders who have promised to deliver more sustainable, people-oriented economic growth. Manufacturers of lead-acid batteries are a key target. An explosion in the use of electric scooters and surging auto manufacturing have driven up demand for batteries, but mining, smelting, making and disposal of the lead and the batteries have been poorly regulated. "It doesn't matter what the reason is, companies and local officials must take responsibility for failing to meet e
