Twitter was expected to remove verified checkmarks from older, non-paying, accounts this weekend, but the social network decided instead to label them as having a "legacy verified account."

The option to either show or hide the Twitter Blue checkmark was discovered in the social network's code by an app developer, but this feature could end up not going live to the general public.
Few details about the new Twitter ad-sharing program have been announced, other than that the money will come from ads which will appear in the reply threads of paid Blue Verified users.
Twitter will add more context to emails it sends to those who are rejected after applying to be verified on the platform. Access to the application is limited for now, but should hit everyone soon.
