That trophy is unique in the history of lichess, nobody other than ZugAddict will ever have it.
ZugAddict was streaming and for the last 2 hours he had been trying to defeat A.I. level 8 in a 1+0 game, without success. I told him that if he successfully did it on stream, he'd get a unique trophy. One hour later, he smashed Stockfish, and I honoured my promise.
