I can't reply to dan's reply to this, for some reason, but regarding "I don't see a distinction there. It refers to submissions, and Apply HN posts were submissions, a.k.a. stories in HN's sense (posts that aren't comments).", well, it also says that users should vote for "a story" because it's "intellectually interesting", which is not a rationale (or in the case of "story" a referring term) that seems to make much sense in the present case. So it makes a lot of sense, I think, to construe it as referring to submissions in the narrower sense.

Regardless, the tweets in question were around a long time before Pinboard was disqualified without expectation. The first one certainly predates kevin's phone call, for instance.

(And of course one of the tweets in question was contained a link to the general poll, which was not a submission of Maciej's, and the other, technically, was a link to all the Apply HN posts, not to his.)

I don't see a distinction there. It refers to submissions, and Apply HN posts were submissions, a.k.a. stories in HN's sense (posts that aren't comments).

Certainly it never crossed my mind that the rules about voting rings would be any different than with regular posts. HN users are passionately opposed to the voting system getting gamed; we'd have been skinned alive if we allowed it. But tptacek makes a good point about that not being obvious to everybody.
