Twitter Implements Login Requirement, Restricting Access to Tweets and Profiles
Originally Published 2 years ago — by Mashable

Twitter has started blocking visitors from viewing tweets, profiles, and other content on the platform unless they are logged in. The move, which began rolling out on Friday without any official announcement, is seen as a way to increase user sign-ups and potentially inflate user numbers for advertising purposes. The decision may have been influenced by Twitter owner Elon Musk's disapproval of AI companies using Twitter's data. However, the move could have drawbacks, such as reduced visibility on search engines and potential loss of traffic. It also hinders researchers who rely on scraping Twitter for open-source intelligence and studying hate speech and disinformation. This is not the first time Twitter has limited platform accessibility since being acquired by Musk.
