Leslie Jones has spoken out after the man who bullied her off Twitter (and was subsequently banned from the website) received a book deal.

White nationalist and alt-right poster boy Milo Yiannopoulos has landed a massive book deal with a reported US$250,000 ($346,000) advance, prompting many to criticise publisher Simon & Schuster for elevating the voice of the notorious Breitbart editor.

Yiannopoulos made headlines last year when he was permanently banned from Twitter for organising a targeted racist and sexist harassment campaign against Ghostbusters and Saturday Night Live star Leslie Jones.

The website's technology editor was responsible for drumming up hatred against the star, with his followers sending in tweets comparing her to a gorilla and insulting her appearance in mid-July.
