I don't think it is a problem. If so, I am also in deep doo-doo, as I sometimes link to my Hubs both here in the Q&A and on others' Hubs. Furthermore, I have no objection to others linking to theirs from mine, as long as their Hub is somewhat (even loosely) related.
I think Bat eyes was asking about comments on Hubs. The page relache noted was about the the FORUMS, not Hubs. And even that page didn't say anything about one's Hubs at all -- only about links to elsewhere.
