Without a link, it's hard to evaluate this. I doubt you're getting "ghostbanned" for mentioning "unpersons". But this is posted under a throwaway account, so there should be no risk to posting both the link and the name of this supposed "unperson". Go ahead and clear things up for us, would you?

Somebody else on this thread seems to believe that HN will ban you for posting stories critical of Bobby Fischer. You can see why people are jaded about claims like these.
