Where are the faqs for industrial music?

Backmasking was used by Frank Zappa in his earliest albums to avoid censorship. We're only in it for the Money (1968) contains the backmasked message "Better look around before you say you don't care/Shut your f***ing mouth 'bout the length of my hair/how would you survive/if you were alive/shitty little person?" at the end of side A. This profanity laced verse of the song "Mother People" was not permitted by the record publisher, so Zappa, edited the verse out (as well as the word "fucking", ironically), reversed it, and inserted it elsewhere in the album as a "song" called "Hot Poop."
