Lost Media that you know you will never find

I would list mine, but I have said it on personal lost media, so go check it out there.

Not holding out much hope for the missing ancient texts that were used by the Borborite and Carpocratian sects of Gnostic-Christianity. I particularly lament the loss of On Righteousness as well as The Greater Questions of Mary and The Gospel of the Hebrews at the moment.

Nor am I holding out much hope for The Magnificent Ambersons (1942) at this point, sorry to say.

Same with Him (1974), and I'm skeptical my probe into Not Just Another Woman (1974) yields fruit.

No, but I'd love to be proven wrong someday and I don't want to discourage interest in the search with my pessimism. But it seems clear there was one print of that film, maybe two at best, and anyone who'd care enough to know what they had are dead or dont have it. If it ever turns up, it'll probably be a weird fluke thing like someone buys it at a yard sale and flips it on ebay without anyone knowing, or it turns up in a landfill or condemned building 20 years from now in a severely degraded state with no way to restore it.

I kind of doubt that this subject would be popular enough for an article (and I wouldn't make one for it anyway because I don't think that the creator would be happy if I made one without permission), but there's a fairly popular cat breeder on YouTube who I know of, and for multiple years they had an online newsletter about their cats. The newsletter was eventually discontinued, but the breeder still kept up an online archive for them in case any fans were interested. The newsletters dated back to the mid-'00s and were interesting to me because they documented when the breeder first got some of their permanent cats, and they featured photos of since grown-up kittens that the breeder sold, and photos of the parents of some of the breeder's permanent cats. One day, the archive suddenly disappeared. I tried using the Wayback Machine to access the newsletters, but literally only one of them was accessible. On YouTube, I asked the breeder about what happened to the archive; I can't remember exactly what they told me but it involved either a hacker or not being able to afford keeping the archive up any longer (maybe both).
So, all but one newsletter from an archive of newsletters that I thought were interesting have probably been lost forever. I was a bit surprised that the breeder didn't try harder to keep the archive up, but oh well.

Also the game “Cosplay-Talia” it’s a mobile game with magical girls in it. You match blocks by connecting them and you could customize the girls with outfits. It’s super obscure and has discontinued. All I have are names of the VA’s, a Youtube video and some pictures from Google

Any old fanarts/fanfics that haven’t been archived in any way
