We know that link-only answers aren't really appropriate, and that the links should ideally be used as citations against the text that is provided in the answer itself. But what if that link is to a downloadable file rather than a website?
I have seen a recent post where the answerer (a first-time poster) gives a summary bit of text that provides some degree of answer, but with a link to download a zip file (from their own website) that allegedly covers off more detail and reasoning.
Now, we could remove that link as spam, but then the answer text itself would not have any evidence supporting it. There's not much point asking them to summarize the content of the file, because they're more or less done that with the answer text. But I'm not sure if I'm comfortable leaving up links to download zip files from users personal webspace.
Are such links appropriate?
