A pair of popular third-party Twitter apps are the latest to fall victim to the company's increasingly tight API restrictions.
Tweetro, a third-party app for Twitter developed for Windows 8, has been denied permission to exceed the recently-introduced 100,000 token (user) limit.
This ceiling-user level is a policy used by Twitter on apps developed by external companies.
The Tweetro app, developed to manage Twitter overload, has reached the upper-ceiling of 100,00 as of last week. The app has been unsuccessful in its application for an exemption, which means that new Windows 8 users will be unable to sign-up.
Twitter has been incrementally tightening its restrictions on apps which access its timeline in an attempt to direct users to its official suite of apps and Web services.
In an email to New-Zealand-based developer Lazyworm, who developed Tweetro, Twitter stated: "As you know, we discourage developers from building apps that replicate our core user experience (aka "Twitter clients").
"We know that there are developers that want to take their passion for Twitter and its ecosystem to unique undeserved situations. As such, we have built some flexibility into our policy with regard to user tokens – which went into effect September 5th, 2012."
The email went to say: "Unfortunately, It does not appear that your service addresses an area that our current or future products do not already serve. As such, it does not qualify for an exemption."
“Future” is a key term here as Twitter have yet to release an official client that plays on like-minded terms with the new Windows 8 UI.
Alongside Tweetro, the other app to be hit by the 100,000 user-ceiling is Tweet Lanes.
Developer Chris Lacey has ceased further development as a result of the ruling. He announced to Tweet Lane users: "It saddens me greatly to announce that going forward, I won't be actively developing Tweet Lanes as I have to this point."
Going on to state: "The cold hard reality is that with this immovable, 100,000-user ceiling, my plans for growing and eventually monetising the app are no longer feasible."
Lacey acknowledged that it will be disappointing news for many users, he made it plain that over the 10 months he worked on the app in his spare time, so the decision “pains him” more than anyone else.
Twitter’s tightening of their API changes will come into effect as of March 2013.
As evidenced by these developments, the company is already working hard on enforcing them.
