I’d bet good money that a skilled malicious actor could find out exactly who you or I am within a single day. Most people don’t even use anonymous email addresses, and any admin log showing their email address, combined with an IP address, would make tracking then down trivial.
I used to have a VPN subscription, but most of the places I really wanted to block just blocked me instead. Lots of important services didn’t work, and it was a constant pain. So I just let the subscription expire when it ran out.
