As we know well, this tag is a moderator-only tag. Regular users cannot apply this tag to a question.
Teresa, however, did not have a diamond at the time of post creation. This tells me that staff members have access to certain moderator-only privileges without requiring a diamond (♦). Diving into the FAQ on privileges, my suspicions were confirmed:
Stack Exchange staff members have the ability to edit tags on any site without having to submit it as a suggested edit, and can modify moderator-only red tags on meta sites without needing to be a moderator.
This makes sense, as some Stack Exchange developers who do not have a diamond might need to edit reported bug posts to have a status tag, but it leaves me curious as to where the metaphorical lines are drawn.
I searched around for some information on the subject, and when I came up blank, I asked for some clarity in chat, and wasn't given the clearest answer.
We know that staff do not need to have diamonds on all sites their account is a part of. We also know from the list of current Community Managers that CM's in particular are (with the exception of Nicolas Chabanovsky) moderators network-wide.
With the addition of the staff tag to an employee's profile, there's a slight lack of clarity between what a staff member can do and what a moderator can do.
Not much discussion around staff abilities exists, which is why I ask...
- What privileges or tools do diamond-less staff members have access to?
- Are extra privileges granted on a manual, on-demand basis internally? (Inspiration for this question from Mithical in chat)
- From Robert Columbia: Are staff members immune to question and answer bans?
- Are there any other privileges granted? Or, are such privileges granted on a manual basis (per 2 above)?
