Catbox.moe became the place we used on Reddit after Imgur dropped NSFW stuff. Seems to work well enough.
Catbox has been slow sometimes for me and on some webm it forces you to download it instead of playing it in a web player. It works but it feels very alpha
I've been posting a fair amount and catbox is where I've ended up. Once you make a free account you can track your uploads. Let's Lemmy be light weight server side and catbox gets help with funding from the community
You could try pixelfed, but you'd need an instance willing to host your content.
As for traditional file hosting I've been using catbox for anything over 1MB.
I posted nude stuff to Pxlmo set to unlisted and they haven't complained or taken it down so far? It was kinda unclear to me whether that was against their rules or not 😅
That said, maybe a Pixelfed instance specifically for nudity would be better though, then you could have it be visible on both platforms.
I think our best bet for that one is bugging the lemmynsfw admins for something like pics.lemmynsfw.com Maybe we can chime in with them to see if that's a possibility or if someone knows of a R18 only pixelfed instance
Could I suggest self hosting? I’m surprised nobody ever mentions it. But you could: spin up a simple file server, use an S3 type service with a CDN, run an open source project like pictshare.
