I couldn’t find any tools to check this, so I built one myself.

This is a little site I built: the Defederation Investigator defed.xyz. With it, you can get a comprehensive view of which instances have blocked yours, as well as which ones you are federated with.

The tool is open source and available on GitHub. Hopefully someone will find it useful, enjoy.

    You get a list of the instances that have defederated from you, and you mount a coordinated attack against them

        No I’m just saying how this can be used in an attack. I’m certainly not advocating attacks of any kind.
