This question probably mostly applies to meta, although it might be relevant to the main site.
The question prompting this question can be found here. No doubt it was perfectly sensible at the time, but the phenomenon it alludes to has gone, and there is only one answer (looks as though others were deleted) that is also useless without context, and contains broken links.
I've already tagged the question for mod attention (or tried to) without result. Is the policy just to leave this sort of thing lying around? I would have thought cleaning up as we go was a better idea.
