But why not kick them out? Why bother with a shadow site for them?

If they don't know they're being quarantined, there's no reason for them to find a way around their block. They'll eventually tucker themselves out and move on to whatever their internet equivalent of burning ants with a magnifying glass is.

The same reason people get shadowbanned. If they know they are banned they will attempt to work around it.

One day I'll find out that I've been shadow banned from HN, and all of you were bots all along, lolz
