The Unwritten Rules Of Instagram: Do's and Don'ts

14.Don’t steal other Instagram users’ content

Just because you like someone else’s photo doesn’t mean you can post it as your own. If you want to utilize user generated content (UGC) in your strategy, have users tag you or use hashtags on their posts. When reposting, always, always, always provide proper attribution. There are some third-party apps which will allow you to repost another user’s post to your account while giving proper attribution to the original user.
