Where, exactly? His Twitter feed contains a single link to each of his original Apply HN and the later poll (plus one link-less joke about the poll). I mean, yes, he has a big following, and yes, he promoted his application (which everyone involved admits he would not have done if he had thought it was against the rules). But "explicit and repeated" makes it sound like a lot more than one (humorous) tweet per poll.
And it's not like he used a personal account, either. That one doesn't mention it at all. It's just @Pinboard - and frankly, it would be weird if you didn't think current customers would want to support you in growing your business.

And sorry, claiming they were just jokes can't be a free pass. Everything about that application was framed as a joke from start to finish.
I think it is dodgy to have an online election, and then disqualify participants for mentioning it to people who might want to vote for them.
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.
I told him when I noticed the same Twitter post that it was going to cause problems (too late!), and he was genuinely surprised.
Your rules about voting rings are not public. I think that you're so used to modding the site that you forget this, but take a look at the letter of what it actually says in the FAQ.
I'm confused by your second paragraph—I just don't get it—but if there's a way to make the FAQ clearer I'd like to. There's no question that I have trouble seeing this stuff from an outside viewpoint. I'm too immersed in it.
By the way, I didn't reply to the bit about the voting rules because I think it's the only important point in your post; it isn't. It's just something that I knew how to respond to. I'm trying to write something in response to the larger substance, but am having trouble because my feelings (bad, and sad) have the better of me right now. I'll get there.
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.)
But that says nothing about the Apply HN situation. That's new, had a different set of rules (hell, you wrote a polling solution), and the regular guidelines didn't necessarily apply. That they did should have been made clear.
Again, nothing against it this time, since it's all up to you guys - just feedback for the next time.
