We know that when you downvote a post, you lose 1 reputation. This makes sense because you don't want people randomly downvoting questions without a strong reason behind it. But I have a few doubts and if what I think is right, then a few suggestions.
When a downvoted post is found to get closed, reaches so many downvotes that it becomes shaded in white, or deleted by the one who posted it, you will gain back your 1 reputation. If not, wouldn't it make sense that way that the lost reputation is regained for raising a 'good' downvote and not a bad one? And maybe you can even receive +1 reputation if this happens?
Well, maybe 1 reputation is a very small amount to even care about, but still, this is just a doubt I had.
