Sometimes new users ask one question after the other, all of them quite redundant etc.
SO allows to downvote, or close such questions. But closing only punishes the answerers that just happen to prepare an answer. And downvoting very quickly is denied (that is, undone) as it is considered "serial downvoting".
Now, there is this new user. My downvotes here were now detected as "serial downvotes". So it would have been better not to do anything.
What is the right way to handle this situation?
