The 69-year-old actor announced on Friday (18Nov16) he was going to stop using the site after Twitter suspended multiple accounts who were reportedly associated with a controversial political group.

Those with extreme right wing views, called the alt-right in the U.S., are allegedly posting tweets on the social media site supporting and inciting white nationalism, homophobia and anti-semitism.

A number of alt-right Twitter users, including white nationalist Richard Spencer, and alt-right personalities Ricky Vaughn and John Rivers, have had their accounts suspended for writing tweets that break Twitter's new hateful conduct policy.

Woods, who boasts more than 484,000 followers, said he was dismayed to learn accounts had been suspended, and bemoaned the end of free speech.

"Since Twitter is now in the censorship business, I will no longer use its service for my constitutional right to free speech," the actor wrote in his last message.

Wood's post was accompanied by an image of a USA Today article with the headline, "Twitter's alt-right ban may backfire."

The Oscar-nominated actor also updated his bio to read, "Twitter has now sadly abdicated its position as a sole beacon of free speech. Voltaire's famous dictum has been quietly buried by these left wing savages."

The Once Upon a Time in America star was previously embroiled in a $10 million (£8 million) lawsuit after he sued an anonymous Twitter.com user, @abelisted, last year (15) for alleging the star is a "cocaine addict" after he posted a series of messages about media priorities.

The anonymous user later died of unknown causes in October (16). Woods responded to the news by telling a Twitter user he hoped the defendant had died "screaming my name, I hope. Learn this. Libel me, I'll sue you. If you die, I'll follow you to the bowels of Hell. Get it?"
