Twitter took a few more small steps in its ongoing fight to curb harassment on the site Thursday, announcing in a company blog post that it is expanding the ways it can crack down on people who use the platform to harass others.

"We streamlined the process of reporting harassment on Twitter recently; now we’re making similar improvements around reporting other content issues including impersonation, self-harm and the sharing of private and confidential information. These changes will begin rolling out today and should reach all users in the coming weeks," wrote Tina Bhatnagar, the company's vice president of user services.

If a Twitter account is set up to impersonate someone else, or if an account has leaked someone's Social Security number to the Web, anyone can now report it -- not only the person being impersonated or the one whose personal information is compromised.

Bhatnagar also said that Twitter will add "several new enforcement actions for use against accounts that violate our rules" and that those actions will empower the company to discourage bad behavior and deal more effectively with chronic rule breakers. For example, users banned from the site may have to give Twitter a phone number to begin using the service again. Such a move could help to curb the "whack-a-mole" problem Twitter faces now, where users simply create new accounts when their old ones are shut down for harassment.

The post did not say whether those extra enforcement options might include banning particular people from Twitter -- something the site has been loath to do in the past, but was mentioned as a possible solution by chief executive Dick Costolo in a leaked internal memo last month.

"We're going to start kicking these people off right and left and making sure that when they issue their ridiculous attacks, nobody hears them," Costolo said in the memo, as reported by the Verge.

Twitter has faced a harassment and abuse problem for years and has been criticized for not dealing with these issues more quickly. But in the past year or so, the site has taken several steps to give users more tools to deal with online harassment and some anti-abuse advocates say the company seems more open to hearing their concerns -- what those advocates see as a welcome, if overdue, first step.

Since Twitter first began overhauling its harassment policies, Bhatnagar said, the company now reviews five times as many reports as it used to and has "tripled the size" of the team devoted to supporting abuse victims.

And the company isn't done adjusting its plans, she said. "This week’s changes are the latest steps in our long-term approach, and we look forward to bringing you additional developments soon."
