Posting this here rather than in Apache because I'm not asking "How to" but "Whether to":
If you've got a page with legal/copyright type information, is it a good idea to make this page visible to everyone including nasty robots that you'd normally lock out? (Same principle as robots.txt: let 'em see the rules so they have no excuse for not obeying them.)
Could be considered to be a indicator of quality to search engines - copyright, privacy, about us pages, etc. Same basic principle as standardising name, address and phone number across local search citation sources.
Wouldn't worry about thin content for a couple of (fairly important and commmonplace) pages.
