Not just your instance. Every instance Federated with it that got a copy of your post is part of the chain of evidence. Don't plan crimes in the fediverse for heaven sakes.
Given that the Fediverse is wide open, unencrypted, and your instance owner is no more immune to getting a subpoena from law enforcement than anyone else ... one might think twice about asking questions of the form "if I commit a crime can they find me" here. Even if your VPS can't detect it, you just left a paper trail here by asking how to commit a crime. :) Bad plan.
Your Fediverse instance owner might consider deleting your post and perhaps your account to keep them from being the subject of such a subpoena in the future.
Breaking the industry out of the ATX motherboard rut was a great thing. Glad they did it.
And can instead move to a platform that is controlled by a rando instance owner with their own set of quirks and foibles. And can choose amongst thousands of such instances, each controlled by a different rando with a different set of quirks and foibles. Out of the frying pan and into the fire indeed.
While ranking the misdeeds of billionaires is a tricky business, given the choice I'd say Zuck is slightly better than Musk at the moment. :)
Nailed it.
Then there's the absolutely abysmal UX of following someone who exists on another Mastodon instance when you're linked to their profile, which involves the non-obvious steps of manually copying and pasting a URL into a search box on your home instance, waiting for a connection to be made, then following them, at which point you won't see any of their old posts, just their new ones. Compare and contrast with Twitter's handling, which is where you search for a username and can see all their posts and can follow them without having to manually copy and paste a single damn thing.
