The San Francisco-based popular micro-blogging site Twitter recently announced a change in its terms of service for developers, thereby banning all third-party advertisers from injecting paid Tweets into the service.

As a result of the new restrictions imposed by Twitter, the last-month-launched ‘Promoted Tweets’ service – which allows advertisers to place paid Tweets atop user search queries – will practically become the only authorized way advertisers will be able to place their ads within Twitter content.

Noting that the changes result from Twitter’s growing concern that if a flurry of ads makes its way to the service, it may gradually turn users off of Twitter as a platform, the micro-blogging site’s chief operating officer Dick Costolo said: “As our primary concern is the long-term health and value of the network, we have and will continue to forgo near-term revenue opportunities in the service of carefully metering the impact of Promoted Tweets on the user experience.”

Formally announcing the new restrictions in an official blog post, Costolo said that Twitter considers it important to protect the core experience of real-time introductions; as well as working towards “long-term success for all advertisers, users and the Twitter ecosystem.”

Meanwhile, most Twitter developers are of the opinion that they would pivot around the new restrictions, and that the changes will not have any sizeable detrimental effect on their business models.
