You’re exposing potential attack vectors, which is particularly concerning if self hosting = home hosting.
Also with home hosting, it’s probably against your ISP’s TOS. It is for mine (I actually read it!). Will they do anything? Probably not. But it’s a risk.
You could face legal issues if someone posts illegal content, since you’re hosting it. Even unwittingly.
Those concerns are what stop me. Because I otherwise think I’d enjoy hosting a little corner in the fediverse.
My tenuous understanding from an article I read about the AT protocol but barely remember is that it can’t be fully decentralized. I think you have to use bluesky for user authentication. And I think it said the hosting hardware requirements would be significant to the point where it’s not very feisable. I welcome corrections/clarifications.
Point is, assuming that’s reasonably correct, true decentralization isn’t possible. And by it’s nature as a big corporate owned site, enshittification is inevitable.
Risk is also a factor re: self hosting.
