My LinkedIn is filled with effectively bot accounts. They seem real, but it’s low grade and all within three degrees. And they look like real enough, at follow or accept connection point I have no way to really know. And worse, I have colleagues who accepted them and make them seem more legit.

That's where I need a negative signal, too. Public block lists, ways to disregard somebody's follows or only consider the first 100 follows each, etc.
