Yes.

But your instance must be running v19.

If it is, you should be able to add servers to the blocklist in account settings. If you are using an app or client which doesn’t implement instance blocking, you may have to do this in the webUI In a browser, but once you do the block will work in any client.

Ok, thanks!

I’m using Memmy, so I’ll try to login on the web someday and get that server instance blocked. (Presuming we are running v19+, not sure)

You can add instance filters manually in Memmy.
