"The way this feature works is, after a photo is uploaded it may prompt the question – do you want to tag this photo – to your friends. If that photo is then tagged, you are notified that a photo of you has been posted so you can check it out. After that, it is up to you what action to take– for example, you can remove the tag or ask the person who posted the photo to remove it altogether," the company said in a blog post.
