Is that worth of all the job? I mean is it really an issue? There is really big chance that any of search machines would ever show those hits. There isn’t just enough content. And who would ever even search such info-level things?
That is basically quite simple thing:
- it public visibile isn’t an option, then visitors shouldn’t see that content either, and visibility should be TL0
- if that content isn’t secret in any means, then you should not care about visits of bots
Don’t make your life any more complicated than it is
