If your account is potentially confusing in terms of its affiliation, we may require you to edit the content on your profile. If you violate this policy again after your first warning, your account will be permanently suspended.

If we believe you may be in violation of this policy, we may require you to provide government issued identification (such as a driver’s license or passport) in order to reinstate your account.
If you are engaged in impersonation or are using a misleading or deceptive fake identity, we may permanently suspend your account.
