Yes, unfortunately, all the replies are true - there is a specific IR topic for Wrong External Link, which, at this time, still needs to be set as "Admin Needed" to remove the problematic link, as only Admin can perform that.
I put in the New Feature request to add a tool to the list of activities we can do to remove or edit these links. I am hopeful that we will have that ability at some point so that Admin does not get flooded with these types of requests. (Although, when he gets a flood of requests, that's usually when new tools get worked on!)
