X is once again expanding its Community Notes feature, this time by adding the option for users to request a note on posts they think might be containing dubious claims.
there's a new option in the post menu on desktop for "Request Community Note", and that'll flag that for checking by Community Notes contributors.
As explained by X:

"People on X can request a Community Note on a post they think would benefit from one. When there are enough requests, Community Notes contributors will get notified and can opt to suggest a note. That gives people on X who aren't contributors an avenue to help, and lets the contributors know where notes might be useful."

It might be a good way to dissuade misinformation in the app, making it easier for users to actually seek out notes rather than only relying on the ones that are available under the current system. Of course, that also depends on users actually going to the effort of making such a request but could be a really good supplementary process over the Community Notes system.

This means that for a user to request a Community Note they will be required to have a verified phone number attached to their profile, which incidentally requires X Premium subscriptions.

Accounts will initially be allowed up to five requests for notes per day, although X says that this may be increased if requests end up driving more helpful notes.

Community Notes is one of the top innovations that has been boosted by Elon Musk since he took over the app, developed under Twitter as "Birdwatch". As it appears, studies show that Community Notes can prove helpful in the fight against misinformation and in reduction of amplification of false claims.

The only concern now is, though, that X is relying far too heavily on community notes to shoulder all the content moderation burden now that Elon Musk has gutted the company, cutting 80% of its staff.

Many of those chopped roles were in content moderation and safety, with Musk hoping to cut the company's overheads by putting more reliance on crowd-sourced fact-checking and feedback. That also aligns with Musk's view that X users should be the arbiters of ultimate truth, not X management, which is another reason why Musk's pushing Community Notes as the key solution in moderation.
But investigations have found Community Notes is not able to cope with the entirety of moderation mandates across the app, thereby letting misinformation take off and pushing alternative narratives, unchecked by much.
And that could be a major issue as the U.S. election is approaching soon, and we've already started seeing conspiracy theories and misinformation gathering steam via X posts early in the campaign.

And thus, while Community Notes is a great system, which does deliver many benefits in one regard, it may not be enough to tackle all of X's content detection and clarification work.

But that's what X is using, and we'll see how that sits with it during the election push, and then what's in the aftermath, as this campaign promises to be divisive in every sense of the word.
