No Comment

"A huge majority of user-generated comments to blogs and forums are malicious, while tools are largely ineffective.

"Websense's biannual `State of the Internet` report revealed that 95 per cent of user-generated comments to blogs, chat rooms and message boards are spam or malicious. Websense Security Labs also identified a 233 per cent growth in the number of malicious websites in the last six months and a 671 per cent growth during the last year.

"Looking at Web 2.0 security trends, the report found that the websites are increasingly being used to carry out a wide range of attacks, and claimed that `efforts to self-police these Web 2.0 properties have also been largely ineffective`.

"The report said: `Websense research during the period showed that community-driven security tools (asking users to report inappropriate content) on sites like YouTube and BlogSpot are 65 per cent to 75 per cent ineffective in protecting web users from objectionable content and security risks.`"
