Often the target of abuse on social media, author Chetan Bhagat hit out at "cyber bullies" saying that Twitter was in fact the "graveyard of bullies".
"Trolls have made Twitter negative to a point where celebrities have stopped talking much on the platform," he said claiming that action of those on social media who target celebrities stemmed from a "mob-like mentality".
Mr Bhagat also claimed that the presence of trolls - someone who leaves an intentionally annoying message on the internet, in order to get attention or cause trouble - was forcing celebrities to shift to other social media platforms like Instagram.
Predicting the end of the widely popular short messaging service, Mr Bhagat said: "I think Twitter is going to suffer and in five years it will close down like Orkut and Myspace. People are moving to platforms like Instagram, because of all the negativity on Twitter."
However, Mr Bhagat himself continues to remain active on Twitter, with 9 million followers. He explained he only does so for promotion of his books, and not for sharing his personal views anymore.
"Only writers and media persons are there on Twitter, all the celebrities have disappeared. When I release a book I go there (Twitter) knowing that the medium is like a minefield and it has only become negative. People use my name to write negative comments and get a few laughs, so I also use it for publicity," he said.
Not all of his efforts at promoting his books, though, seem to have worked.
When he asked people to post images of latest work - One Indian Girl -against beautiful settings many mocked him by posting insulting photos.
Some posted images of Mr Bhagat's book on a weighing scale, with old newspapers and magazines in balance. Others superimposed the cover of his book in the hands of ISIS terrorists about to execute hostages, and forcing others to read the book.
The 42-year-old author said social media for him remains a place where free speech must be cherished.
"Writers are supposed to say what they feel is right. Sometimes it could be pro, sometimes anti- government. Writers who say I am only going to take an anti-government position are stupid. If it a corrupt government I will criticize it. When it acts against terrorists it has all my support," he said.
