If you’re one of those people who uses Twitter to be abusive and harass other people, Twitter has its eye on you — and you could find yourself completely locked out.

The social media giant has introduced an enforcement option that will allow its team to lock out abusive Twitter accounts for a certain period of time, or at least ask a user to confirm a phone number and then delete offending tweets, according to an Inquirer report.

Twitter is trying to crack down on situations where multiple users harass a person or group of people, or just users who employ violent threats to attack people they don’t like.

Shreyas Doshi, who is director of production manager at Twitter, said that policy that dealt with direct and specific threats against others has been extended to promoting violence against others as well.

Twitter will also test some new technology that will help identify some of these trolls, taking into account signals and context that “frequently correlates with abuse” — such as the age of the account and the similarity of the tweet to others flagged as abusive, Doshi said.

It’s the latest in a series of steps that Twitter has made in order to improve the safety and security of its service, following on the heels of an effort last year known as Get Safe Online that updated anti-harassment tools and made it easier for users to report abuse.

The move follows one of the more high-profile cases of Twitter abuse: an effort to get Jane Austen immortalized on the UK’s £10 note by Caroline Criado Perez, who was targeted by a man and a woman who allegedly sent 50 abusive tweets an hour for 12 hours, which ended up landing both of them in jail.
