I get an average of 100 spam comments a day on this blog, and sometimes they are very amusing. I don’t know if they just randomly pick words, or there’s a formula, but this title I particularly liked.
There is an Anthology of Spam Poetry with a nice collection of different poems, along with info on their authors:
Your second youth
blue pill premier.
Also, Andre Codrescru has a nice audio essay on spam poetry you might enjoy.
