Answer that only contains a link to jsFiddle
What should be done about jsFiddle only answers? Whilst jsFiddle is great, even expected for relevant tags it still suffers from all the usual problems of link only answers and the consensus seems to be that jsFiddle only answer should be handled as link only still. It seems to be a losing battle fixing it on the social engineering side though, but technical solutions have been ruled out too, even though those behind it seem helpful and responsive. (Embed and mirror automatically would have been my preferred option here)
I put together a data explorer query, based on an older query to find some of these. Some of them have been fixed since the last data dump. Some are now deleted, but there's an awful lot still around in that list, even some with comments asking to expand them into a full answer. Towards the end of the list some of them get better, but a lot still have no text with them at all.
That's an awful lot of answers - clearly too much for a crude mass-flagging attempt. What should be done? What can be done? The idea of manually fixing 5000 answers is not attractive, I don't much like the idea of a mass-purge (although flagging new questions/answers seems sensible), a URL ban hurts everyone even those who write good answers and give a fiddle.
Maybe a language specific quality filter is needed? (E.g. block short+no code+jsfiddle link with a suitable message).
