Tweet

In a Blog post entitled “We hear you,” Twitter’s Senior Director of Trust & Safety, Del Harvey, announced on Monday that the company has introduced the ability to file reports from an individual tweet on its iPhone app and the mobile version of the site with plans to add the feature to its desktop and Android versions.

“While manually reviewing every Tweet is not possible due to Twitter’s global reach and level of activity,” wrote Harvey, “we use both automated and manual systems to evaluate reports of users potentially violating our Twitter Rules.” Harvey said that the changes were made “three weeks ago.”

The post said that there are more than 400 million Tweets sent every day worldwide that appear on their site, on apps and embedded in other sites.

The announcement follows an online petition campaign on Change.org demanding that Twitter “Add a report button to Tweets.”  The campaign was reacting to the case of  Caroline Criado-Perez, a British activist who, according to the petition drive ” has been targeted repeatedly with rape threats on Twitter,” as a result of her efforts to get the British government to keep women (other than the Queen) on banknotes.  Those efforts, according to the Guardian, resulted in Jane Austin’s picture on a £10 note.

Twitter maintains a “safety tips for parents” page and has advice on how to block abusive users.

Disclosure: Twitter has made a small grant to ConnectSafely.org, a non-profit internet safety organization where Larry serves as co-director.
