I actually got to wondering why some dead accounts got killed, when I see acceptable to good content from them. It is only when I go back through the comment history far enough, I can sometimes see what got them pushed over the edge. But other times I don't see anything really bad, so my assumption is that some other automated heuristic kicked in (posting from low reputation IPs), or that what got them banned ended up deleted. I know you can sometimes vouch for a comment, but it would be nice to be able to click a button that gives an explanation of why an account was shadow banned (assuming that doesn't violate privacy or something).
