Nobody from scamwarners called him or anyone. What undoubtedly happened is that another woman he was trying to con found the posting here, and confronted him with it. Now he is angry because he lost a chance at getting that woman's money, and he hopes that with some bluster and completely absurd threats, he can somehow get you to remove the posting. In reality, he is a low-life petty coward who hides behind stolen photos and fake identities.
As Bryon said, just ignore and block him. If he keeps trying to harass you, please feel free to tell him that the information is in Scamwarners' control now, and tell him he can contact me (the email address in my signature.) I'd be happy to have a chat with the little worm.
As for the threats of a lawsuit? I always love it when scammers threaten to sue me for exposing their lies. I usually offer to walk into the police station with them. Of course, in reality they can't do a darn thing, because (a) you haven't lied (which alone is all that is needed); (b) they can't file a lawsuit against you for posting their name and photos when the name isn't theirs and the photos are stolen; and (c) walking into a courtroom or a police station and showing their face would immediately land them in jail.
