I'm glad to see that most people are figuring these scammers out.  Yes, they're like freaking mosquitos.  As far as I've read, they're probably in Pakistan.  They get names off some list they bought, and they go down the list and call and annoy the &(*!#@\ out of people.  They often call using Skype and leave callback numbers that I assume are probably connected with Skype or something similar (though I don't know that).  Many people already have gone to the FBI, etc., and they essentially tell people to log the calls, which I'd guess most of us do anyway to some extent.  The only two things I've found get them off my back for awhile are the truth--that I and many others have figured them out, and I explain what I know--and sheer mockery, just flat laughing at the latest attempt by someone who knows he's lying just as well as I know it.  The last time I just laughed right in their faces and told them I knew they were full of it, suddenly they got mad and instead of a "law firm" they were "bigtime terrorists who know Osama bin Laden" (their words, not mine) who were going to rape my wife, my daughter, my sister, etc.  That just confirmed to me they were liars so I laughed harder, and then told them I was "done playing with them" and hung up.  They left me alone for about three months after that conversation.  Now sometimes they try, but not usually quite as hard as before.  I don't know if they forget they've already tried some of us or they're just hoping they can lay off for awhile and we'll forget, or maybe their organization just has a high turnover rate.  I'm hoping these scammers have enough brain cells to Google the numbers, names, and pseudo-legal nonsense phrases they use as well, so that they can see it isn't working.
