Earlier quoted context omitted.
Security of user accounts is no joking matter. It may be hijacked for spam bots. Someone may pose as you telling stories.
Spam bots are a legitimate concern to me. I'll probably start rotating passwords if I sense that something like that is happening. I don't want to hurt hacker news. And somebody could already pose as me, or you, or anybody else on here who isn't way famous (nobody could pose as pg). Anybody can be anybody else on the internet.
In this case I can see why some people downvoted you. But otherwise, downvoting should be reserved for spam/malice and not for a differing opinion, not even for one that you totally disagree with.
