What's the Deal With This?

What's the deal with these kinds of e-mails? Spam?

I've been getting them for the past months I guess, but since yesterday afternoon they just keep coming and coming. When I woke up this morning I had 21 new e-mails of which 20 were such stupid e-mails containing text like:

My question: what's the point in these e-mails. They don't sell anything, they're just random text. And it's friggin' annoying because Gmail's spam filter doesn't recognize them.

During the writing of this e-mail I already received 3 more! Aaargh!

My Gmail's spam folder now contains 3052 e-mails, which means that in the past 30 days I had that many spam messages. That's over a hundred a day, this is getting crazy!
