I had flagged a spam-like answer with type Other (which allows you enter some detailed description) in SO, and it appeared with an
active tag in my profile. https://stackoverflow.com/users/flag-summary/2995038
Few minutes later, I founded the flagged answer deleted (perhaps by the user himself) and I couldn't view it anymore but in my profile the
active tag was still there. I wonder how reviewer/moderator can see it. If they were unable to see it, would my flag become something like a "dangling pointer" ?
