"Over four months, I’ve drafted 65 notes debunking conspiracy theories on topics ranging from airplane crashes to Ben & Jerry’s ice cream. I’ve tried to flag fake artificial intelligence-generated video clips, viral hoax security threats and false reports about an ICE partnership with DoorDash.

Only three of them got published, all related to July’s Texas floods. That’s an overall success rate of less than 5 percent. My proposed notes were on topics other news outlets — including Snopes, NewsGuard and Bloomberg News — had decided were worth publishing their own fact checks about.

Zuckerberg fired professional fact-checkers, leaving users to fight falsehoods with community notes. As the main line of defense against hoaxes and deliberate liars exploiting our attention, community notes appear — so far — nowhere near up to the task.

Feeds filled with inaccurate information matter for the 54 percent of American adults who, according to Pew Research Center, get news from social media."

There are currently hundreds of notes published to Twitter (x) every day, Coleman said, and while he doesn’t have a target for how that might change once AI is involved, there could be a “significant” increase. Twitter (x) first debuted a crowd-sourced fact-checking program when the company was still known as , and well before Musk’s 2022 takeover. But its focus on has increased under Musk’s ownership, and has recently been adopted by other companies, including Platforms Inc. and Ltd.’s .

Musk himself has said Community Notes serves as a bulwark against , calling it hoax kryptonite, but he is also regularly by the fact-checking process for posting misleading information.”

The top Community Notes contributor is...an antivirus startup?

indicator.media/p/the-top-comm (£)

Curious tale about the system on X/Twitter, which arose out of some analysis Alexios, Zara and myself are doing on CN. It seems like one antivirus company got so frustrated with the lack of response from the X about scam posts that they decided to pump their notifications through as CNs so people could be alerted about harmful content that way

IndicatorThe top Community Notes contributor is...an antivirus startup?I thought someone was gaming X’s crowdsourced moderation; instead, they appear to be helping clean up the platform’s mess for free.

Community Notes Can’t Save Social Media From Itself

bloomberg.com/opinion/features

on the X/Twitter data suggests
- CN are getting faster, but are still slow (median is +14 hours after original post)
- A smaller % of notes are being published (personally, not sure that is bad if overall submission number is up)
