I went back and read some of the admin discussion of the rationale for deleting references to internet discussion forums.  It makes sense, but in the case of this deleted instance, the reference was not pointed to the discussion, but to a photo of the house.

I would just undo the revision, but have some suspicion that a bot will keeping targeting it.
