For Kbin, you might want to check out the @kbinStyles magazine. Folks are creating tweaks for Kbin in the meantime that improve functionality like this :)

I guess for the privacy conscious and content creators, one solution of this would be to host your own instance just for yourself. You control the domain and what’s hosted. I could setup @[email protected] and store my content on my server. In much the same vein as custom emails - [email protected] could be my email (technically I could have [email protected] but that could be confusing with only a dropped @ but anyways).
Obviously this is not going to be a solution for everyone and it would be good to have a way to backup your content and be able to move it between servers. But in the mean time, it’s a workable solution for those who find it important enough to go down that route. 🤷🏻♀️
