Enough already

Is it just me, or has anyone else noticed a huge increase in the number of spam e-mail messages of the "I am a foreign national with a large amount of money I want to get into the United States and if you will only send me some cash/an airplane ticket/all your financial information I will cut you in on a large percentage of it" variety? I used to have one pop up in my inbox every so often, but lately there's been something like one a day. Did I accidentally leave my e-mail address somewhere that put me on the "greedy, gullible idiot" list? It's hard for me to believe that anybody still responds to these come-ons, if anybody ever did in the first place, but surely having so very, very many of them out there dilutes any impact they might have had. I mean, having five or 10 exotically named people offer up this unbelievable deal in a week, with only a small variation in details, might make even a greedy, gullible idiot suspicious. Diversify, spammers! Show some originality!
