vvvexation | Apparently, they want nothing from me (Reply)

I just finished my sporadic spam-folder check, and once again I am bemused. In addition to the usual offers to "bigger my short d1cck" and one attempt to convince me that I've won a lottery I never entered ("we don't sell tickets, we just use a 'cyber ballot system' to pick a random email address as our yearly winner--because we want to 'reward individuals who spend their time and resources surfing the web'")--oh, and one notice from a bank where I don't have an account, telling me they might have to suspend my account unless I clear up these reports of suspicious activity (read: tell them my credit card number), and quite clearly addressed to ten people besides me *snerk*--I've also received two pieces of blank junk mail. No subject, no text, and no sender either--so it's not even possible to reply to it.

Is this just a preliminary attempt to see which addresses don't bounce, or what? You wouldn't think they'd need to bother with that, right?

It's actually kinda eerie. I feel like it must be a setup for something weird, 'cause if it isn't, I can't explain it at all.
