The loser posts their own photo to Reddit's r/RoastMe, holding the required handwritten sign, and lets several million strangers finish what the league started. The thread stays up permanently and the league reads highlights aloud at the draft. The internet roasts harder than any friend group.
The long haul: this is not a one-afternoon sentence. With a time commitment of one hour, permanent record, the punishment keeps paying out (for everyone else) long after the season ends. Long sentences need a written end date and a league-appointed enforcer who checks compliance.
