The best way to get full access to fediverse data (including e.g. voting) is to run your own instance. So what instances, do we think, are operated by bad actors, irrespective of their identity or nature❓🤔
Or to get more conspiratorial, a bad actor would need one or more big instances to collect that info without sticking out. So which big instances, do we think, would be willing to give, or sell, a "bad actor" full access❓😉
(This of course assumes that none of the big instances were created by bad actors).
In any case, if you're posting overton wrongthink™, and not doing it (pseudo-)anonymously, then you're doing it wrong. I mean, you're in a network/platform that goes as far as encouraging you to use multiple accounts, so what's stopping you from doing it right?!
LLM's and stylometry are not magic.
i write using different styles constantly.
And It's not like people are writing original long essays here all the time, for the weapons grade tools to assay anything with high confidence.
