A couple days I just got some downvotes and to be honest with this new hints I actually didn't get any hint. First some people just downvote and don't even wrote the reason.
Based on one of your sentences
"Your post could have been down-voted for various reasons. It might be unclear, poorly-written, incorrect, incomplete, or have any other problems that caused a community-member to cast a down-vote. Users who earned enough reputation points are allowed to down-vote posts whenever they feel the post in its current state is not useful to the community."
Here is one of the Questions I made. I already search on some fansites and there is no info is this is possible, we make the quest yesterday and I want to build the mount. (This is just and example there is much more questions of me and others users that don't have any hint/real reason of the downvote)-
Anyway, IMO if for someone the question is unclear, poorly-written, incorrect, incomplete, or have any other problems the person who downvote should say what's wrong, cuz if there is something wrong isn't like is posted knowing is wrong.
I already made the suggestion and I believe isn't only me who have same request. I started to contribute on the site since January and I stopped some months cuz I just saw how others give downvotes as candys on Halloween, and also see how noone improve this.
... Anyway, I just wanted to express what I think about this kind of situation, hoping this change.
