Vote
Nobody here is real, and all we learn is which of the two you picked.
Which of these two invented characters would you pick? Every answer builds the World Class 100.
The vote needs JavaScript, which this browser is not running. The two characters and their profiles read perfectly well without it.
How the pair is chosen
Whichever two characters have been compared least, so coverage spreads evenly instead of piling onto whoever is in front of everybody this week. No scale to calibrate and no mark out of ten: a lone number has nothing to anchor it, and a second character does.
What comes back
The split for that one pair, and nothing else. Not a position and not a place in a table, because no table is published yet. The arithmetic, the scheduled recomputes and the parts of it that cannot yet be trusted are in how the World Class 100 works.
What a vote stores
A winner, a loser and a timestamp. That is the whole row, and no account exists and no address is kept, hashed or otherwise.
Your browser keeps one thing of its own: a single entry naming the pairings you have answered and which of the two you picked. It never leaves the browser. The page is handed several pairings at a time and picks one you have not answered yet, so we are never told which ones those are and could not tell you if you asked. No cookie either, and that distinction is real rather than a dodge: a cookie rides along with every request to the server, this rides along with nothing.
It is there for two reasons. Coming back to the page gives you your own answers instead of a blank slate, and you are not shown the same two faces while pairings you have never seen are waiting. Clear your site data and it goes, with nothing lost that we could put back, because we never had it. What the privacy policy promises holds on our side: a vote reaches us as a winner, a loser and a time, and nothing in it says who sent it. It costs us the obvious thing. The same person can vote as often as they like, nothing here prevents it, and we accept that rather than overlook it. The defence is the batch recompute rather than a fingerprint.
Who you are choosing between
Everyone in Profiles was written by us and every face was generated. No character depicts, is modelled on or is named after a real person, and nobody here is offered or available for anything. That is the appeal of the format rather than the small print underneath it: a list of who wins, with nobody on the receiving end of losing.
