Wayback is useful when we find someone who scraped our content say 2 years ago, and we have to show their webhost what our site looked like 2 years ago, and also that we had the content up first.

It kills the scammer's argument when they claim they had it up first, when you can show it on wayback archive 2 years before the offending web site domain name was created.
