Or someone is trying to slip messages past bayesian filters trained to
allow pgp messages. Most of these spams are awarded insanely high spam
scores by spamassassin.

I've been getting spam with blocks of text strongly resembling pgp
signatures appended for years now. Got about 250 of them last year.
And, amusingly enough, they seem to keep up on their patches (the
versions of pgp seem to keep up with the official releases). Still,
the signatures would never verify, as there were invalid base64
characters in the signature block.
