Not sure what that is - time to file another bug report?
Anyway I have been thinking about the possible combinations of Open to Goodle, Guest access and RSS feed and a currently working on a Truth Table

Open to Google
I think that this is a decision for Moodle.org as a whole – we could discuss this but it’s unlikely to change at all I think and certainly not in the short term therefore I have highlighted Open to Google N options in Orange for 'moodle' decision.
(From Moodle config variables page)
“If you enable this setting, then Google will be allowed to enter your site as a Guest. In addition, people coming in to your site via a Google search will automatically be logged in as a Guest. Note that this only provides transparent access to courses that already allow guest access.”
However, we can make changes at level of Moodle lounge config and Social forum config.
