Questions that are apparently closed by only one mod seem to generate some tense discussions, mostly in comments and some more appropriately on meta questions. Several mods have been accused of closing questions on a whim, and / or going against the communal philosophy of SE.
I'm intentionally not including the questions / discussions that caught my eye as to not point fingers and as I think everyone has come across something similar at least one.
I guess its quite understandable that seeing a "Closed as whatever by SomeMod ♦" note is not as welcomed as a "by User1, User2, User3, User4, SomeMod ♦" note. So how about adding the number of flags to the note? Something like:
Closed as whatever by SomeMod ♦ (flagged by 3)
