Exactly! If you have some free time on your hands it's time to have a little fun with them. Start out acting dumb, pump them subtly for as much information about them as you can get and then identify yourself as an officer of some scary sounding US Government Cyber Law Enforcement Agency and scar the living dog doo out of them. If you can get it on tape and or screen shots then by all means share here. Especially report any web sites they want you to visit. A good time could be had by all.
I just got one this morning!
“Hello - we are from the IRS and you are going to have the police come to arrest you for a warrant for noncompliance of tax code for the amount of $3000...blah blah”
I usually tell them I want them to l*ck my b*lls or something even more vile and horrible if I can think of it.
