Surprisingly if you browse HN with "showdead" on, you'll find quite a few people don't realise. Others realise but keep posting comments they know most people won't read (you can tell in some cases because occasionally someone will mention their ban in comments).
(I browse with showdead on because the volume is small on HN, and every now and again you come across people in the former category who were shadowbanned for one or a few incidents relatively far in the past, who since then seem to have acted reasonable, where it's worth pointing it out so they can appeal their ban - mostly the flagged comments or shadowbans are well deserved, though)
