Who watches the Birdwatchers? Joke aside that's an experiment I can appreciate at least it will show us how bot invested and deranged twitter and it's users really are. I actually thought it was launched months ago..
This is a tad different from the previous approach which involved third-party fact checkers that were, uh, visibly slanted towards the Democrats to put it lightly (and whenever a non-Democrat-aligned news source got blessed as a fact checker by a masjor social media network there was a major media storm over it).
That'll end well! ;) Problem is that on Twitter people aren't "regular", they're either seeking their own echo chamber for confirmation bias or the opposing echo chamber to insult, so crowd sourced feedback will simply be used as a tool for either of those.
That's great for making Wikipedia safer from abject misinformation, which is a huge plus. It's less good at ongoing discoveries and news.
Regardless of whether he actually did it I think this is a fatal flaw that will prevent birdwatch from ever being trusted.
I see the fact check still there.

The note wasn't removed. It's still visible as a potential note; it just dropped below the threshold necessary for general display. This is not common but it's not abnormal either; it happened to one of my notes on a controversial topic.
However although users get a permanent id it's not possible to get actual Twitter handles from these ids. So identification of who the birdwatchers are is not easy (wisely so)!
