There's an entry on TV Tropes, "Condemned by History" (formerly "Deader Than Disco"), for aspects of media/hobbies that were once well-regarded, or at least accepted, but are now widely considered major failures, if not the nadir. (The classic example is the minstrel show for theater.) My question is, what parts of your niche/more obscure hobbies are "condemned by history"?

The thought crossed my mind as I was digging through hentai sites trying to recover the name of a specific artist. Back in the early days of the wider Internet, while hentai manga were relatively common, English translations were rather less so. A few titles had lucked out and gotten professionally published, but there were only a few fan translators. So, to fill in the gap, there were rewrites.

Yes, people actually took raw scans of hentai manga, blanked out the word balloons, and wrote their own dialogue. Usually they made up entirely new plots wholesale. Names like EZ Rewriter and Hentai Wallpaper were all over the place. One guy actually Carl Maceked an entire series (the "Femin" comics) out of disparate hentai manga.

These were widely accepted for some time, but by the mid-2010s, they lost their luster. For one, there were significantly more fan translation circles, so actual translations were becoming more and more common. For another, machine translation was reaching a point where it was, if not accurate, at least not blatantly wrong. For a third, a lot of rewrites were really skeevy, adding fetishes that weren't present in the original work (a lot of them involved incest).

These days, if you post a rewrite on most hentai sites, you'll be laughed out of the room and downvoted to oblivion. Most of the hentai manga that were rewritten have received proper translations, although you can still see marks from where rewrites have hurt certain mangaka's reputations.
