Many times I see questions which are wrongfully tagged, but I don't have the slightest clue about what tags they should be.
Generally by people who have absolutely no idea what the topic they tagging is about (common example is set-theory tags for things that are not even related to elementary set theory, but rather combinatorics and such).
Should we have a tag for wrongfully tagged questions, so the more experienced users could follow and properly retag the questions?
