By any chance did you buy something from a "Information 4 Profit eBay Store" recently? I just got an e-mail - which referred to me as Adam Riggins - thanking me for some purchase I certainly didn't make. It also mentioned that I joined some sort of mailing list and it has links to other sites for making money.
Maybe we have similar e-mail addresses or something, or maybe it's just spammers at work. I was just trying to make sure since I've had this address for several years and only recently started receiving bulk mail.
