Twitter reinstates white nationalist Richard Spencer

Twitter has reinstated white nationalist Richard Spencer, one month after he and others associated with the "alt-right" movement were booted from the social media service. Spencer celebrated his return with a triumphant tweet on Saturday. The return of the public face of a fringe white nationalist movement comes as Twitter struggles to strike a balance between protecting free speech and curbing abuse. The social media service rarely comments on why individual accounts are suspended — and why some are not. For years, Twitter billed itself as the "free speech wing of the free speech party." But it's been under growing public pressure over its failure to stop hate speech and harassment.
