Twitter has this thing called “Community Notes.” It used to be called “Birdwatch.” Basically, if someone posts a claim that's misleading or factually inaccurate, and that tweet picks up traction, a select group of users have a special power to add context notes to the bottom of the tweet.

It's often seen in the U.S. on posts by politicians. It even corrected Elon Musk once.

And now, it might be coming after advertisers.

The CEO of the media firm EZPR posted a screenshot on social media today showing that Community Notes corrected a claim made in a paid advertisement on Twitter.

The ad was from the financial software firm Quicken:

This isn't the first time it's happened, but it's one of the few times it's happened with a major brand.

Last year, someone spotted a promoted post claiming that Tesla's stock was crashing because the autonomous driving function wasn't safe. Immediately below was a detailed response — not posted by Elon Musk, but by this Community Notes feature. (And, let's not kid anyone, probably written by someone at Telsa.)

It's also not the only platform to do this. Facebook's approach is to cover up the creative with a big blurred out screen, reading “False Information.”

Imagine that on your next creative.

Or, maybe it's an opportunity? How long before someone designs an ad that looks like a platform corrected it, but it actually was just part of the ad?

And would the correction tool need to post a correction indicating that the correction in the ad was fake?

And you thought AI was going to complicate things.
