I want to delete my account
For security reasons, we cannot delete an account on behalf of a user. You must have access to the account in order to delete it from our Account Removal page:
When you delete your account, your photos, comments, likes, and friendships (everything) will be removed permanently and will not be recoverable. We cannot reactivate accounts. Additionally, you will not be able to sign up with the same username again.
