Definitely not, I used it for random questions, in regular, expected way. Only the accounts that prompted about the square were removed, even if the ask:base64 pattern wasn't used. This is something I explicitly looked for (writing a paper on censorship)
Did you just notice you transitioned to your alt account on HN too?
Seems like something you do often. Grab a few accounts in every website you make an account regardless of the ToS.
I comment on HN from pc and mobile. Made temp account when I wanted to comment. I have no use for an account so it lives as long as the cookie lives, since I haven't entered an email. I was not aware this is against ToS, I'll look into it and maybe ask dang to merge accounts and add an email to them.
