It seems that one-line answers, even when they are linking to a page with a good solution, are increasingly frowned upon.
If the reviewer is unable or unwilling to edit and expand the answer to a full paragraph, what flag should be used in the reviewing?
One line answers themselves aren't necessarily bad. "To fix this foo the bar" is an answer. Not the most descriptive answer, but is one. Don't flag these. I don't downvote these, but you are free to if you really feel you should. I don't see any reason why.
When an answer is nothing but a link and some text, e.g. "yo, check out my blog for the solution [link]" then it should be flagged as "not an answer". A quick any easy way to test this is to imagine the answer without the link. Does it still try to answer the question? For example:
You need to foo the bar, see my blog [link]
This is an answer. If you remove the link most of the answer is still there. This meanwhile:
to fix this see my blog [link]
is not an answer. If we remove the link no useful information remains.
I find Shog9's illustration of this to be quite helpful:
I would also advice to comment about it how answers should be made an actual answer.
Editing the answer and including contents of the the link though ... don't.
If it is the only answer I myself might/would include an answer myself.
