You keep saying "bad" but perhaps it's more like... "critical"?

That said, if you don't like something, why go to the trouble to rub someone's face in how you do not like it, rather than simply scroll down and move on with your life? Maybe even leave the community, block the OP, etc. - not liking something is not an ideal reason to downvote it, imho.

And the reason for that is that on the receiving end, someone getting a bunch of downvotes without anyone bothering go explain why, isn't a great feeling. It leaves them not knowing what it was that people disliked, and with the feeling that people are judging them but not before bothering to do a proper assessment. i.e. that the community is unfriendly towards them, maybe even full of people with a childish mindset.

I haven't even so much as glanced at your history so none of this is a judgement against you: I am just illustrating why a lot of people prefer to downvote responsibly, and therefore why someone might want to know what your "Attitude" score is, so that they can more properly pay attention or ignore when you interact with them - e.g. if you downvoted everything then someone receiving a downvote would not "mean" so much compared to someone receiving the literally only downvote that someone else has ever delivered.
