There's already rabbit holes of fake MMA fighting you can fall into online? Even if you're a "fan" and relatively aware of what to look for ... still difficult to spot? Horribly, had the same sensation while watching UFC at a bar. "Haven't I seen this match where they fall on the ground and hug for hours before?" Mostly empty background audience with limited reactions.

Somebody took AI video editing, and in a year or two, we're already at entire MMA rabbit holes of fake videos.

Commenting mostly as a personal evidence reference of how crazy the World Wide Web has gotten from anecdotal sources.
