The number of spam mails sent during the first quarter this year broke all records after a series of hacker attacks left the personal information of hundreds of thousands exposed.
The computer security firm Jiransoft on Sunday said a sample survey of customers revealed that spam mails accounted for 94.5 percent of e-mails sent from January to March, the highest percentage since the company started the survey in 2005.
According to Jiransoft, the proportion of spam mails has gone up every year, from 86.8 percent in 2005 to 92.63 percent in 2007. Sixty percent of spam is about pornography, followed by general advertising and credit loans.
