I heard of a scam recently - likely not all that new - where ladies, or not, will post multiple ads and just wait for guys to message with their real numbers then try to link those numbers to their real ID. Once they do that they infiltrate their friends list and try to get the guy to send dick pics, messages, etc., then threaten to expose him to his wife, family, friends, and employer.
This is why I have a little chuckle every time I see the ridiculous restriction of "no text apps" in escort ads...as if that very escort isn't using a text app herself lol.
