Well, this is weird... I went to answer your question, but I don't remember how I originally set it up, so I looked into my settings. My RSS feed in vbulletin points to a feedburner URL that I apparently created. The Feedburner URL being leveraged for this feed (it's a FB page feed, not a profile feed) is http://www.facebook.com/feeds/page.php?id=[insert your page id# here]. I removed my particular # but that's the format. Weird thing is, when I try to go to that URL, I get this response:

Format not supported.
This feed URL is no longer valid. Visit this page to find the new URL, if you have access

Yet my feed actually works. You can't explain that! :-)

To solve my "noise" issue I am now using the "RSS Feeds as Posts" mod, so that when my bot relays my FB page activity, it simply replies to an existing dedicated thread rather than creating a thread every time. It's working well.
