Instagram recently added a new feature that allows business or creator accounts to easily keep track of Instagram Stories that mention their profile, and to re-share such content in the business' or creator's own Stories stream.  

This new capacity could be an important development for brands who are interested in re-using user-generated content on their own feeds, or who want to more easily keep track of promotions entries that mention the brand.  

As always, even though this new functionality makes sharing technically possible, brands will still have to contend with rights-clearance issues presented by the re-purposing of user-generated content on their own feeds.
