Online dating sites report a surge in activity in the days before Valentine’s Day, as many singles use technology to find a match. Bao Vang with the Better Business Bureau (BBB) of Minnesota says that also means more scammers are ready to dupe users into believing they have found love.

“The way they’re doing that is creating backstories, full-fledged identities, and then they’re tricking you into falling for someone that doesn’t actually exist. That term, you may be familiar with is called “catfishing.”

Vang says if it sounds too good to be true, it probably is. She says never send money or personal information that can be used for identity theft to someone you’ve never met in person. And never give someone your credit card information to book a ticket to visit you.
