Actually, I can't think of any occasion where such
a link would be
beneficial to the project. What exactly did you have in mind?
Let's suppose there was an RFA candidate who had posted to one of the
aforementioned sites some questionable material. Would it not be
beneficial to the product to point this out, and would, in some such
circumstances, a link be necessary? And don't forgot my ArbCom
case/lynching. Do you seriously mean to imply that it was absolutely
wrong of the arbitration circlejerk to link to an alleged personal
attack I made against you that was posted on that forum?
There may be other occasions, not related to bad-faith or questionable
actions on the part of people, where a link may be beneficial for the
purpose of discussion. While I can't exactly think of an examples, such
a situation certainly could appear.
