The most common target of online dating scams are women over age 40 who are divorced or widowed, according to the FBI.
Bernardo offers these tips to steer clear of any so-called sweetheart scams:
- Don't provide any personal information right off the bat, including your home address, work details and educational background.
- Do a quick Google search to see if the information your match provides lines up with what you can find online. A person without an online presence is a red flag.
- Don't use passwords with publicly known information for online dating profiles.
- Do get a second opinion from friends and family who can be objective.
- Don't respond to any requests for money or loans of any kind.
- Do trust your instincts. "If a profile seems too good to be true, then it probably is."
If you believe you are the victim of an online dating scam, report it to the dating site and file a complaint with the FBI's Internet Crime Complaint Center.
