I've been here for about a month and I've already realised how easy is to downvote for no reason and how some people freely do it.

This may cause some problems sometimes (mainly for questions) as a `-1` near your answer/question will lead into some "hate" on you and also the lost of `rep`. 

As I said, I've been here for a short period of time but I already saw how a well formed question gets downvoted for no reason, [this one][1] is an example of it.

So, my question is, as title says, should downvotes be moderated in any way?
