I think everybody have met with the fact, that usually closed questions, specifically not constructive questions get the most upvote.
It wouldn't be wise to forbid voting on these questions, of course. But what about not giving any reputation for votes if they go for a closed question? The whole system would probably be not too easy. But I realized that some users go for reputation with questions of this type.
When I see an answer from someone having a huge amount of reputation I think he/she has the knowledge and is wise enough to take his/her answer into consideration. But having one popular not constructive question - this doesn't mean to me what reputation means otherwise.
I read some posts about automatic downvotes and I hate them for many reasons. I think that leaving reputation unchanged would be OK for this type of questions.
What do you think?
