Tweetbot and other third-party clients stop working as Twitter 'intentionally' blocks API access
If you are a Tweetbot user who found yourself unable to access Twitter, you're not alone. Tweetbot, along with various other third-party Twitter clients stopped working on Thursday, it seems as though this is the result of an intentional block by Twitter.
Although the company has yet to say anything to either confirm or deny that third-party access to the Twitter API has been blocked, it is something that has been confirmed in leaked internal communication from Twitter engineers. One says: "third-party app suspensions are intentional".
