The ban against Mr. Yiannopoulos, a technology editor at the conservative news site Breitbart and known by his Twitter handle, @Nero, follows a campaign of prolonged abuse against Leslie Jones, a comedian and co-star of the recently released “Ghostbusters” movie.

Hundreds of anonymous Twitter commenters hurled racist and sexist remarks at the star’s Twitter account, rallied and directed by Mr. Yiannopoulos this week.

The average person spends more time on Facebook than any other leisure activity surveyed by the government except watching TV and movies.
