This question contains a list of tags that are not useful and should be removed from any question should they appear again. This applies mostly to so-called meta tags, see also The Death of Meta Tags for more information.
If you see a new tag like this please remove it from the relevant question and add it to this list. We'll also try to keep a counter how often the tags reappear to keep track of the most problematic ones. Please only add tags that you really encountered, don't preemptively add bad tags that haven't appeared yet.
