arrgghh!!! i got a scam email from all three of these "names" within two days. i only responded to one saying "i'm completely booked that weekend" and i didn't respond to the others. What the heck?!
They send those out all the time. It has nothing to do with whether you respond or not, they just randomly send them and hope that someone takes the bait. I like to mess with them if I have time. I have a page on my blog where I post the emails that they send me back.
