Duplicate content across mulitple domains, with no index


If i use noindex on meta tags, on duplicate content, will I be safe? For example


I use a SSO system, with shared community forums. Certain forums are shared across the network, but those shared forums, have noindex in them, except the first forum (flyffworld.com) which was the forum that had all the threads first.

How would google treat my duplicate content, even though I have noindex. Should I also use nofollow as well?

Opps, sorry, can a mod merge this. I can’t edit the thread no more for some reason. I meant to point to the forums.
