(WHAS11) -- It's a spreading scheme dubbed "Insta-scam."
Young fans are targeted when they visit their favorite celebrity’s Instagram pages.
Here's how it works: cyber thieves post promises of big bucks in the comment sections on celeb-posted pictures. Then, the scammers ask you to get pre-paid debit cards and give them the security pin on the back.
The scammers say they'll add money to the amount already on the card. But the scammers don't actually add money they take what's on the card and disappear.
Experts say you can avoid being duped by these scammers by never giving out your pin number.
