Aw, I was looking forward to seeing my profile and having you save me the trouble of compiling some of that data for myself.
I’m not going to out my instance for everyone to know it as the one to defederate.
Should be fairly straightforward to figure out, if I was interested. I'd create an instance of my own and have it present slightly different information to each of the other instances that federate with me, probably creating a different fictional user to send a few votes from to each of them. Then just check to see which of those fictional users shows up in your data and your data-collection instance's identity is revealed.
