The practical consequence of slapping a silly name on a tournament is that you select for people who click on jokes, not people who stay for arguments. My opponent's cheap test is confounded: change the name, change the audience, so any signup comparison measures self-selection, not engagement. That's not a real effect size, it's a biased sample. The cost isn't zero either, because a credibility hit is hard to reverse. Until someone runs a controlled trial measuring retention and debate quality, not just shares, the safe default is still to reject the proposition.
