Reminder that it doesn't matter how splintered your data is, how many different accounts you have, or how much fake info you have in your accounts. They have a unique "fingerprint" of your behavior (using your outputs to the network), and can match identity very accurately with very little information. It doesn't matter if you switch IPs or use a VPN, unless you're switching like crazy often, they will be able to generate and match the fingerprint. It doesn't matter how large the population of internet users are, either, they can pick you out.
