They come in all shapes and sizes and use any means possible first to scare and intimidate you and then to separate you from your hard earned money.
There are email scams that inform you that you’ve won big prizes or that you’ve come into a gazillion dollar inheritance, all you have to do is send some money to cover the taxes. There are phone scammers claiming to be from MicroSoft, the IRS, Medical Device Companies, you name it, they are endless.
The phone ID’s are “spoofed”, they look like a local number, maybe even that of your local police/sheriff’s office. Spoofing done in an attempt to scare you in to picking up the phone.
This scam has been around for awhile but seems to have just surfaced in my neck of the woods so it’s worth mentioning again since it’s targeted specifically at registrants. If it hasn’t gotten to your area, it probably will sooner or later so beware.
