Twitter launches another bid to tackle bots and abuse after years of promises

As harassment and misinformation remain rampant, CEO Jack Dorsey asks for 'help' with platform's health

Twitter has asked for help in tackling the rampant harassment, bots, misinformation and polarisation in a more strategic way so that it can improve the "health" of conversation on the platform, the company's CEO, Jack Dorsey, said on Thursday.

"We aren't proud of how people have taken advantage of our service, or our inability to address it fast enough," Dorsey tweeted.
