I think it is not very difficult to check the websites which spreads hatreds. Most important thing is people should not encourage such websites. For example, if they stop visiting the site, the add goes dwon so the revenue. But in the case of rediff. It looks like such topics have become the major source of income for them. I also understand that majority of these comments are coming from US IP address and server domains. So most of them are people abroad. In addition I guess people in India spend net judiciously as they have spend from their pocket. Where as in US it is free as most of them are working in some companies and net is unlimited if u get the connection. So it is the clear case of misuse of net.
