"Orkut is used by many destructive elements to spread canards about India, Hindus, our gods and cultural heritage," said Abhijit Phanse, president of Bharatiya Vidyarthi Sena, the student group.
"We are gently telling Internet cafe owners that it is their responsibility to see that surfers do not use their facility to carry out such hate campaigns," he said.
"Or else, we will have to do that job for them." Last week, dozens of Shiv Sena workers vandalised some Internet centres, saying they were not stopping their customers from accessing Orkut groups involved in sending hate messages.

Phanse said his group was developing a special software that Internet service providers could install to block any message containing certain words and phrases such as "I hate" or "I despise". "The software should be ready in 2-3 months"
