I have an account, they're using my first name to directly target me (which is making me incredibly uncomfortable), and they're telling me I ran out of free articles this month and are asking me to upgrade.
I've never had a Medium account. I had no idea an account was something you'd need, other than for posting stories. I use Pale Moon as a browser, with Noscript, uBlock Origin and Flashblock. (As a rule of thumb, if I can't read it in Pale Moon with those running, it's probably not worth reading.)
