As with any technology that we use, there usually comes a time when you need some tech support for large or small problems that may occur. Unfortunately, for much social media, you will not readily find a telephone number to call and speak to a real person about your problem. However when that happens, unfortunately many people turn to the Internet to search for a tech support telephone number and end up getting a telephone number for a scammer who will induce the victim to make a payment, often by iTunes gift cards, which are particularly popular with scammers these days.  Other times the scammers trick their victims into providing personal information that can be used to make the person a victim of identity theft.
