Twitter owner Elon Musk has implemented a limit on the number of tweets users can see per day.
The restrictions were intended to prevent unauthorized scraping of valuable data from the site.
More than 7,500 people reported problems using Twitter on Downdetector, a website that tracks online outages, due to service disruptions due to the restrictions.
Twitter recently changed its behavior and now requires users to log in to view tweets and profiles.
Elon Musk described the restrictions as a temporary measure to address the problem of data theft, which was affecting the service for normal users.
Unverified accounts were limited to reading 600 posts per day, while verified accounts could scroll through up to 6,000 posts per day.
The higher limit for verified accounts is part of the $8 per month subscription service.
Twitter's revenue has declined since Musk took over the company and laid off employees.
