I still don't get why someone who uses their downvote (manually or by delegation) would need to be a regular poster, or even just tell who they really are. Weirdly, nobody cares about upvote trails and looks at all the accounts in there. There are upvote trails with >1000 followers, many of them long dead.

We don't have influence on the trail, we didn't "create" it and we can't exclude anyone. It would maybe look prettier if they delegated because the list of downvotes would be shorter, but then they wouldn't be able to use their upvotes themselves.
On the flipside, a longer list of downvotes might give more people the courage to use their own downvotes. Idk, I just keep thinking out loud because I fail to see the issue.
