Twitter: 'Verified Accounts' Will Stop Imposters

Twitter came out swinging today against St. Louis Cardinals manager Tony La Russa, calling his lawsuit against the company "an unnecessary waste of judicial resources bordering on frivolous," CNET reports. Co-founder Biz Stone also denied reports that Twitter had settled the suit, in which La Russa claimed emotional distress due to tweets posted in his name. But Stone did promise a new feature, "Verified Accounts," to cut down on imposter tweeting.

Starting this summer, a special seal will adorn accounts verified as belonging to high-profile Twitterers. The feature will start with "public officials, public agencies, famous artists, athletes, and other well-known individuals at risk of impersonation," wrote Stone. As for La Russa's suit, Stone is ready to fight: "Twitter's Terms of Service are fair and we believe will be upheld in a court." (More Twitter stories.)
