I don't like the mob thing either but it's how large group dynamics on the internet work (by default). We try to mitigate it where we can but there's not a lot of knowledge about how to do that.
From an admin point of view it's tricky because (unless I'm high on koolaid?) this is a major technical development, so genuine advances are happening all at once. Too many for me to keep up with.
In general downvotes seem like a relatively poor feedback mechanism because there's no shared agreement on how they should be used. This [1], perhaps ironically flagged, post offered feedback on why people downvote, and it's just all over the place. Even if there are guidelines, people will be people. At least with something like clear adjectives, the percent of 'intended' feedback would be higher.
