Why does my Instagram username or profile photo show in some ads to my friends?
Your profile picture or username may be paired with an ad to show your activity on Instagram (example: if you follow a brand's Instagram account). Keep in mind that your username and profile picture will only appear to the people who have permission to view your likes or follows.
Keep in mind that it's against our advertising policies for advertisers to use your username directly in an ad. If you see an ad that you think might be using your username in a different way, please report it.
