A lot of it has survived in datadumps in various places, which I have mixed feelings about. I have no problem with personal collections, but free-for-all is not quite right to me, especially if there is a live version of a fic still available on a public archive like AO3. I will acknowledge that those sorts of dumps have rescued quite a few fics, including a couple of mine that were 'lost' when H&V went down.

On the other hand, some people think they're 'saving' fics by uploading them to AO3 without the authors' permissions and THAT is a naughty thing. And don't get me started on the ones who post fics to wattpad because "I wanted it here". (I have filed several DMCA takedowns.)
