Evil Bits (15 Apr 2003)

When putting my email address on webpages I usually have it as aglREMOVETHIS@imperialviolet.org. Spammers have never bothered to try and decruft these addresses because there was always lower hanging fruit.

Well, today I got email addressed to aglTHIS@imperialviolet.org. I guess the fruit isn't so low any more.

A reply that the author of the `evil bit' RFC (3514) got. Note the company name at the bottom. (it was an April Fool's joke - for those who don't know))

What or who determines the "evilness" or "goodness" of the packet? If a security admin or OS can determine or flag bits as good, what keeps the hacker from spoofing this process by setting the bit to "good"? Does the bit change based on behavior? Or maybe a database with signatures of "bad" bits?
