Beware of Costco, Starbucks and other companies giving away hundreds of dollars in gift cards if you simply share the news on Facebook. Chances are it's a scam,
Scammers use channels, like Facebook and Twitter, just like email and websites to scam consumers during the holidays. Be careful when liking Fan Pages, clicking on fake alerts from friends’ accounts that have been hacked, taking advantage of raffles, ads and deals that you get from “friends,” or installing suspicious “holiday deal” apps that give your private data away.
As always, if it sounds too good to be true, it usually is. Remember not to click on any links in messages from people you don’t know, and be leery of shortened URLs. (You can also use a URL expander to see where the link is taking you before you click.)
