You funny. I've only one account, know nobody on HN, and don't know squat about hellbanning except that it exists. I'm quite amused that anyone would impute such influence & power to me, even as a joke.
Ironically the person behind the account that made those accusations is certainly guilty of at least some of the things he accused you of. Probably a nice example of some good projection. (That account was created just for that post, so at the very least the person behind it is creating multiple accounts.)
