The word spam has spawned off its own corner of the English language.

spamdexing inflating one's rank in a Web index
sping Trackback spam

sporgery Spamming with a forged From line
spambot A computer which sends spam

I'm impressed by how productive the root word spam has become.

Gratuitous cross-promotion: My colleague Terry Zink occasionally writes about spam on his Cyber Security Blog.
