Yes. We have a zero-tolerance policy on impersonation.
If you're on EQUALS — report them with their =username and a screenshot of their profile, either through the three dots menu or via the User Reporting Form.
If you're not on EQUALS — submit a User Reporting Form with a screenshot or link to the profile, along with anything that shows you're the person in the photos being used. Links to your own social accounts are usually the easiest.
Either way our support team will take it from there, review the account, and come back to you if they need anything else.
