using a client that could see and vote in the poll in the 8 minutes that they had it open

The irony being that the ones upset by the API changes wouldn't be using the first party client, so if anything this would have filtered out the people in favor of closing down. I say "would have" because that would require this having actually being what happened. All of those polls I saw were open for days, and the people whining about the closures in the comments just didn't notice because they didn't actually use the site much or were just oblivious as shit.
