Remote instances won’t have your IP or email, and other usage trend data. So that info could only be obtained by this hypothetical tracking instance. As for any remote content on other instances, that can just be scraped by anyone. You wouldn’t even need an account or instance to get that data.
Still think @Buffalox makes a decent point. You never know there could be some cowboy out there, sees a woman getting dragged into a van by masked men, and starts popping off rounds.
