I asked this question here on MSE a while ago, as a feature-request, which later got rejected by a moderator. After doing edits to most of my questions, I thought it would be a good idea to change the original tag into a support tag and to delete the status-declined tag too.
However, when I went to edit the tags, it showed this error:
That basically meant I wasn't able to remove the moderator tag, and I had to add it back, even though I switched the whole topic of the question and all of the other tags.
How can I remove a moderator tag, do I have to ask a moderator to remove it?
