(but I don't think it easily allows blocking the whole instance).

Kbin does have that feature, though I don't think that Lemmy presently does.

Go to https://kbin.social/d/pawb.social

On the right-hand sidebar, or on a phone browser, at the bottom of the page, you'll find a button labeled with a circle with a slash across it. Click that.

I don't really think that this is the long-term solution, though, if people are going to be setting up new instances all the time. That requires work that grows with something like the square of the size of the network. It's the functional equivalent of trying to maintain a Usenet killfile, a solution which didn't scale. I think that what's needed is a way to obtain some kind of feed of recommended and blacklisted content and then for people to subscribe to those easily and for it to be easy to contribute to those. You can choose the feed(s) you want to trust to help guide you to the content you want.
