Twitter to crack down on hate speech, sexual harassment.

Twitter is vowing to crack down further on hate speech and sexual harassment, days after CEO Jack Dorsey said in a tweetstorm that the company is not doing enough to protect its users.

The company has spent the last two years trying to clamp down on hate and abuse.

Dorsey echoed concerns of many users and critics who say Twitter hasn’t done enough to curb the abuse. But others worry that it’s muzzling free speech in the process.
