Yes, anyone can. But unless Bluesky treats it as a trusted verifier then it doesn’t have much practical use.

If you use a 3rd party client like witchsky.app, you can trust or distrust any account you want to be a labeller and verify accounts yourself if desired.

Worth keeping in mind, the original plan was to entirely rely on domain names being used as handles for verification. All ~500 .gov handled accounts on there are almost certainly who they claim to be, unless they are able to set DNS records on those domains.

I guess I don’t appreciate the distinction between verification and an account labeler.
