The latest thing to break is the just-introduced $8 monthlyTwitter Blue tier, which includes a shiny'verified' checkmark indistinguishable from the ones that Twitter used. Any accounts that were created before Wednesday, November 9 will not be able to subscribe until further notice.

As of this writing, what may be true as I type these words may not be by the time I finish this sentence. The company will be doing a lot of dumb things in the coming months with an attitude of rapid iteration based on results, according to Musk.

Twitter Blue terms on Nov 10 noting accounts created after Nov 9 can't sign up for Twitter Blue

Accounts created after Nov 9 can't sign up for the blue program.

The official account label was a second checkmark that was provided to organizations including news outlets and high-profile individuals who are often imitated for scamming purposes. Just a few hours after it went live, it was canceled.

The block on Blue for new accounts seems to be related to what happened immediately after the blue check was provided.

A number of fake accounts pretending to be celebrities, brands and influential people immediately popped up and made audacious, false claims.

Stopping new accounts from getting the blue check is a temporary solution to prevent some of this kind of impersonation, but it's not clear how the company will prevent it. They will probably try a lot of things in public on the platform and seed what sticks.
