ABOUT SCAMMER NAMES
Names are mostly meaningless because there are literally more than a billion fake profiles and fake names on Facebook alone. No one has a magic book that contains the names of all fake profiles.
If you suspect you are talking to a scammer then stop & block them. If you lost money then report it to your local police! Do not confront them – just leave them never knowing what happened, this is for your own safety.
If you sent money to a scammer visit reporting.AgainstScams.org to learn how best to report them.
