I got the ultimate one last month.
The Subject line said something like:
Re: HOt SPring Break Girls! asdfasdflkjasdf.car.Keys
Then the content of the spam was roughly:
REFINANCE YOUR HOME MORTGAGE NOW
asdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;sldifhapsdfjasdfja;
sldifhapsdfjasdfja;sldifhapsdfj
And that was it. No reply link, no contact information, just that gibberish.
What. Does. It. Mean.
?
Perhaps we're seeing the first stirrings of sentience somewhere on the net. All the spam traffic put together has formed a huge neural net which, while it looks like chaotic gibberish to us (like the raw electrical signals in your brain), is actually a highly advanced intelligence.
It could happen.
