Shadowbanning is extremely hostile to users that have been mis-identified as spammers (which will happen) while spammers will quickly and easily figure out a way to determine if they've been shadowbanned. That approach needs to stop.

I've employed shadow banning on an online service deal with some deranged ban-evading individuals. It does help a lot. Granted, some of the more savvy users may figure out what you're doing, but you're often not dealing with the brightest minds. Given that your typical online service will maybe employ one moderator per 100k people, any reduction in workload is welcome.

It should always be a manual action and moderators should continue to see messages of shadowbanned users. You can always lift it in case of a mistake.

If you're going to have a free tier on your service and your service has any sort of interaction going on between users that could be degraded by spammers and the mentally insane, you're going to need shadowbanning. It's either shadowbanning or upping the hurdle to creating an account considerably.
