[Plugin: Restricted Site Access] Still block search engines to stop BP archive

Sounds silly I know, but the thing is Buddypress usually doesn’t show posts from a private ( I would like to block search engines, but allow normal visitors ) blog in the network’s activity. When selecting this plugin’s option , BP still adds content from those blogs in it’s activity, which private blog authors wouldn’t want.

This plugin is really the best though can I put code to add the “block search engines” ability?
