The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. In this regard, Sebi collaborated with the Telecom Regulatory Authority of India (TRAI) to reduce the vulnerability of the securities market to manipulation through misuse of mass communication medium like bulk SMS. In 2018, Russia banned Telegram although it reversed the prohibition two years later. "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels.
