Earlier quoted context omitted.
It is crazy to use your real name to comment on stuff. I limit my real name to GitHub, and even there I always try to comment on stuff like a robot would.
I don't know why you're downvoted, this is literally the first thing we were told about the internet - don't put your real name online. Today you kind of have to, for most things, but generally you should try to minimise the stuff you post attached to your real name as much as possible.
Perhaps it's possible that there's more than one source of advice?
