Fans of the hit Netflix series “Stranger Things” went full detective mode after the series finale, convincing themselves a secret episode called “Conformity Gate” was secretly waiting to drop. The theory spread so fast that more than $15-million was bet on Polymarket, a gambling app, with over $14-million riding on January 7th despite the odds being under one percent. Fans even crashed Netflix trying to access the nonexistent episode, fueled by disappointment over the finale. No surprise episode ever appeared, but the collective chaos became its own kind of shared fandom moment.
