The change has hit Windows Phone users the most as Instagram does’t offer an official app for the platform leaving users no other option other than using third-party apps to share photos through the service.
The issue was first reported by Daniel Gary, a developer who offers Instance, a Windows Phone app that allows users to upload photos to Instagram.
Following the post, a number of people started speculating that Instagram had specifically blocked access to Windows Phone apps offering access to the service. However, an Instagram spokesperson told online publication, The Verge that the service had updated its systems to fight spam.
“We recently made an update to the systems that we use to fight spam to help prevent future attacks and increase security,” said Instagram.
The website now reports that the Instagram API appears to have been updated as users of Instance are now able to successfully upload pictures to their accounts, but the pictures are being blocked from view to other users.
A number of third-party apps, including Instance are using Instagram’s private API, the use of which is against the service’s terms and conditions. So it’s not surprising that Instagram has blocked them through a change in the API.
Instagram offers an official API with restrictions that prohibit developers from using Instagram APIs for any application that replicates or attempts to replace the essential user experience of Instagram.com or the Instagram iPhone App, among others.
Recently, Hipstamatic released the Hipstamatic Oggl app for Windows Phone users that lets them upload and share photos to Instagram, officially. However, it doesn’t let users browse Instagram photos.
