Nope. Content is mirrored and hosted locally, so it's the admin's choice and responsibility.
Moreover, listening to choruses of "individual choice" are how you end up providing a server for people who feel no responsibility to their neighbours and communities. Structural issues require more than "Fuck you, I can do what I want."
You can choose to use a different instsnce if you don't like what the admin's doing. Or you can start your own. That's how you can do what you want.
Edit: I do love the downvotes from the "I can do what to want" crowd, knowing that they're also the "my property, my rules" crowd. Except when they're the ones using someone else's shit, of course.
