That is totally awesome, I didn't know you could submit it like that, many actions in HN are protected with custom/per session tokens. I wonder if it'd be violating HN's ToS somehow... I contacted them for asking about some white-hat stuff, so I'll ask them again about adding something like that, but my guessing is if it's properly labeled as yours it'll be okay. Did you happen to contact them/find affirmative language anywhere? (you are not my lawyer and whatever you say is not legal advice, don' worry).
