Several times in the past few days I have seen questions with answers that seem to completely miss the point of the problem being described in the OP.
I've down voted these answers and then put my own answer which solves the problem (and then goes on to be accepted).
However, on the down voted answer there is the comment by the poster "Who down voted and why?" so I replied to explain why.
Each time it comes with an instant down vote on my answer and no explanation other than something along the lines of "This isn't the right answer" from the person who posted the wrong answer.
Other than just anonymously down voting and not commenting, is there a way to avoid this behaviour? Like I said its happened several times this week and is very annoying.
