Beginning April 1, Twitter will begin charging $84 a year for the Twitter Blue plan.

On April 1, 2019, Twitter will begin winding down its legacy verified program and removing legacy verified checkmarks.

A caveat: This policy will go into effect starting on April Fool’s Day.

Elon Musk has in particular been known for April 1 trolling and has falsely tweeted that his electric vehicle company Tesla had gone bankrupt in 2018.

To keep your blue checkmark on Twitter, individuals can sign up for Twitter Blue.

Twitter Blue is a subscription service that Elon Musk relaunched last year.

The service is $84 a year or $8 a month and provides a revenue stream for Twitter–and needed one, as the platform currently collects virtually all of its revenue from advertisers.
