In this community it might be more accurate to say that people do not like useless negative feedback. I'm perfectly happy to get useful negative feedback, and I think most who participate here would agree.

[ETA: A heavily downvoted post is useful information; it says people don't like what you posted, and this is something you can analyze, ignore, or change appropriately. Mass-downvoting is discouraging without providing anything useful; it says someone doesn't like what you posted because you're you, and that's kind of hard to change.

My personal opinion is that mass-downvoting is basically trolling and that complaining about it is counterproductive for the same reason that responding to trolls is counterproductive.]
