Twitter's political ad ban to limit micro-targeting, putting pressure on Facebook

Ban will come with restrictions on 'cause-based' ads, as Facebook faces backlash over policies

Twitter's rules for political advertising will include new restrictions on micro-targeting, a move that will increase pressure on Facebook, the company announced on Friday.

The policy rollout follows Twitter CEO Jack Dorsey's surprise announcement on 30 October that the company would ban all political advertising due to a belief that "political message reach should be earned, not bought". The new rules will go into effect on 22 November.
