If you use If That Then This (IFTTT) to follow, or should that be stalk, certain Twitter sites, bad news: the free service is having to ditch the feature because Twitter is pulling the plug on what IFTTT can offer.

In a letter to users on Thursday night, Linden Tibbets, IFTTT's CEO said: "In recent weeks, Twitter announced policy changes that will affect how applications and users like yourself can interact with Twitter's data.

"As a result of these changes, on September 27 we will be removing all Twitter Triggers, disabling your ability to push tweets to places like email, Evernote and Facebook. All Personal and Shared Recipes using a Twitter Trigger will also be removed. Recipes using Twitter Actions and your ability to post new tweets via IFTTT will continue to work just fine."

The service has been incredibly handy for journalists, marketers or those keen to save their Tweets for later.

"We at IFTTT are big Twitter fans and, like yourself, we've gotten a lot of value out of the Recipes that use Twitter Triggers," adds Tibbets. "We're sad to see them go, but remain excited to build features that work within Twitter's new policy."

The move comes as Twitter continues to try to rein in what third-party developers can and cannot do.

The social network recently announced that it would be clamping down on third-party apps limiting just how successful they could become, in the hope that people would be forced to use its own offerings.

The latest rumours suggest that the company has stopped development on the Mac desktop app in the hope of pushing people online.

The reason behind all the recent choices is thought to be the company looking to take greater financial benefit from the service.
