It may seem harmless, but liking random posts on Facebook could open you up to unwanted spam and ads.
You've seen the posts. Asking you to "like" or type "amen" to heartbreaking pictures of sick children or "share" for a chance to win expensive prizes.
In reality you could be unknowingly liking and sharing a marketing ploy. Or even worse an out and out scam.
It’s called "like farming" and it's all over the place.
Maybe you saw that Virgin Airlines was giving away free flights.
Did you like that MacBook giveaway post?
All scams according to Consumeraffairs.com.
The Better Business Bureau says marketers set up fake Facebook pages, and get you to like and share them to win something.
When they hit enough likes, they sell the page.
Or start promoting something else.
Then you get hit with ads, offers, and even malware.
So look before you like. And don't expect to get something for nothing.
