If someone has created an Instagram account pretending to be you, you can report it. Be sure to provide all the information requested on the form, including a photo of your government-issued ID.
If you have an Instagram account, you can report it from the app or visit this page on your desktop or mobile browser to protect your account. If you don't have an Instagram account, fill out this form.
Remember that your post is anonymous unless you are reporting intellectual property infringement. The account you reported will not see that it was you who sent the complaint.
Remember to switch on your VPN before proceeding to the complaint form.
