Is the instance public? Is registration open? I would disable registration.

Yes i have disabled registration. Still some unwanted repositories are there. how can delete those unwanted repositories in one go? why is being created?

I would assume someone registered and created them. You’d have to consult the logs.

Otherwise to delete those I would use the API and design some script.

How can I delete it through GUI in one go?

I don’t know if gitea supports deleting accounts en masse through the GUI.
