Make sure that you are able to see their face. Some scammers will talk to you over the phone if you can’t see their face. Most scammers don’t want to use anything that can help identify them. It’s much harder to identify someone by their voice than by how they look. By using a video chat service, you can see the person that you’re talking to and is another defense in avoiding being catfished. One site I love is a company call Safedate.
