Unregistered unable to view threads - does this block web searches also and spiders?

[SpreadingLight]

I'm setting up a forum for prayers and healing. Some of the forums will be general support and talking, and some of the prayer forums might include more personal content.

I'm looking for a way to set Forum Viewing Permissions, per each forum, for the Unregistered/Not Logged In usergroup. I'm currently using Forum Permissions to do this.
This way unregistered guests can view the general forums content, but they won't be able to see the more personal prayer content.


I'm assuming this would also prevent that content from being spidered and available through web-seaches also, yes? If not, is there a way this could be done also (to keep private details off of google and other searches)?

Are there any other ways to keep the thread content private; password protecting folders, etc?

Thanks Much
