Seemed to be:
Something won a vote People running the vote decided they didn't like the outcome so they ignored the vote.
It's basically Boaty McBoatface again with similar lessons of "don't run online polls".
I was tempted to draw that conclusion too, but decided it's important to resist. Finding new ways to productively engage this community is a big deal to us. We obviously have a lot to learn, so screw-ups are inevitable, but we're ok with that as long as we can make them right.
Fooy McFooface is the inevitable outcome of online polls which are open to the entire internet, allow arbitrary submissions, and can have traffic easily driven to them. Other forms of online polling -- high-turnout votes with a preset voters list, polls which are hidden away in unlinkable parts of member-only sites, or polls with a moderated list of options, for example -- don't have those problems.
