But what's your personal spam load?

For myself, I estimate 20% spam. But if I removed the various mailing lists I'm signed up to, it would be more like 95%+

The mailing lists should not count because they've already been filtered from lots of spam so they are biased. My estimate (excluding mailing lists) is 75-80% spam.

MF now has 85% and I have seen 90% quote elsewhere. Botnets have been on a steep rise last 6 months, with 20% home computers in the U.S. alone expected to be zombies or otherwise compromised (theregister articles).
