With a constantly varying algorithm. So they obfuscate, but they never
obfuscate in a predictable way. Which means if you're a spambot, you have to
look at every byte of every page and attempt to de-obfuscate it in every
possible way to see if it's obfuscated. You CAN do it, but you make it
computationally massively expensive.
