Scams and Cons - are rampant, in my opinion.
Here is an audio copy of a voice mail left on my phone. The idiot that left it, was clearly reading from a script, and moreover, failed to listen to my outgoing message. Had he done so, he'd have known he was calling a lawyer. The last fool that left such a message, I called back... and put a little fear into him such that he hung up on me. It was fun. In any event, in this particular scam, you are advised that there are charges being filed against you for tax fraud.
