Twitter knows that it's not enough just to make it easier to report abusive tweets. You have to catch and discourage that abuse as often as possible, too. Appropriately, the social network is rolling out a broader abuse policy alongside tools that help it stop harassment quickly. The new rules now cover all promotions of violence against someone, not just "direct, specific" threats -- Twitter can crack down on more than the most serious attacks. That's particularly important for victims of systematic abuse, who frequently chastise Twitter for being soft on people who clearly wish harm but aren't explicit about it.
