Twitter announces new measures to tackle abuse and harassment

• Expanded efforts aim to stop banned users opening new accounts
• 'Safe search' feature will remove potentially sensitive tweets

Twitter announced on Tuesday that it was expanding efforts to protect its users from abuse and harassment, including stopping banned users from creating new accounts and a new "safe search" feature.

In July, Twitter banned the conservative provocateur Milo Yiannopoulos, an editor of the rightwing site Breitbart News, for "participating in or inciting targeted abuse of individuals". Twitter subsequently suspended the accounts of other prominent figureheads of the "alt-right" fringe movement, an amorphous mix of racism, white nationalism, xenophobia and anti-feminism.
