Anonymous questions - remove blocking
When an asker moves their question to ‘Anonymous’ any and all blocking should be removed for that question permanently.
You can add a confirmation button that informs the asker that blocking will be removed if you think it necessary to avoid mistakes.
The Anonymous feature is being misused in some sections as a trolling method.
With blocking active this allows the trolls to narrow by design the responses that will attach to their (loaded) question.
Since YA does not have the resources to police trolling this would provide a small mitigation.
