Every once in a while I will come across a question that is just so poorly written that I don't think it could be saved by providing critiques and giving the asker a chance to fix it. The most common examples of this are the questions that make completely baseless and incorrect assumptions about historical events, which essentially renders their entire question invalid.
There is not a "very low quality" option for questions; only for answers. Down-voting also doesn't affect a question unless a moderator gets involved.
What am I to do in situations like this?
I do not want to give any specific examples, because I don't want to throw anybody under the bus, especially when I won't be anonymous.
