My.yahoo.com returning invalid URLs for our rss feeds - can we request they be removed somehow?

Hi, I work for The Tennessean and we noticed that the feeds found when you search for Tennessean on "My.Yahoo.com" are very old and no longer exist (inspecting the json response, it also appears the URLs are malformed anyway).  We can't find a way to request the feeds be removed, nor can we find a way to submit new feeds into the searchable index.

Is there a process/form for requesting the removal of invalid feed URLs? Is there a process for submitting new feeds to the searchable index?

Thanks,
