I believe though not from experience that one of the most common methods of identifying a fake is to ask them to send you a photo of them with a specific detail that they are not easily going to find on google. Ie a written sign with your or their name on and the date it was taken. Because it's so specific fakers have a harder chance of managing or will get pissy thar they have been stopped and either not reply or tell you to shove it. Being told to shove it isn't nice but it saves fakey drama.
