Recently, a question and its variants were posted on MSE (and cross-posted on MO as well, if that matters) using different new user accounts:
- A question in matrix polynomial (MO)
Question 2 is identical to question 1 and it was put on hold by some fellow users due to the question's lack of context. Question 3 asks whether the converse of the problem statement in question 1 is true or not. Technically it's not a duplicate, but one can avoid a new question if the "if" in question 1 is simply replaced by "if and only if". Question 4 is essentially question 1, but with a proof attempt (hence it is not "missing context or other details" and it cannot be closed as duplicate because question 1 receives no answer).
No one has yet answered any one of the above questions. I don't feel right about this guerilla tactic, but maybe I'm too pedantic. How to deal with such posting of many slight variants of a question? Is it OK to leave them be?
Edit: There is another stream of duplicates of the same theme, posted probably by the same user:
- A question in compact set (MO)
- A question on polynomial .
