Twitter is imposing a temporary cap on the number of tweets that accounts can see each day, a move that sparked backlash from some users.

Twitter owner Elon Musk tweeted that unverified users will be able to view as many as 600 posts daily while Twitter Blue subscribers can see 6,000 posts “to address extreme levels of data scraping” and “system manipulation.” He later added the limits will be increased to 800 and 8,000 respectively, without specifying how long the limits will last.

Users started reporting issues accessing the social media site earlier Saturday, after they received notifications that they had exceeded their “rate limit.” The number of reports peaked at nearly 7,000 at around 11:30 a.m. in New York before declining, according to Downdetector. Following Musk’s announcement on the limits, the site’s trending topics was dominated by complaints, with users posting about “#TwitterDown” and “RIP Twitter.”

The move follows other limitations put in place earlier this week, when Twitter stopped users without accounts from viewing tweets and profiles. The procedure, which Musk said was temporary, was enacted to prevent people from scraping the site for data.

Musk has made a series of changes to Twitter since buying the company and stepping in as CEO in 2022, perhaps most notably through the introduction of premium accounts that charge users $8 per month, called Twitter Blue, and the ability for users to create subscriber-only content.
