or it’s just instance-specific, ie, one could just ban the instance personally
Instances can ban you without others being affected. Your comments could be visible on one instance and not on another, so there’s a level of shadow banning going on.
Real shadow banning isn’t implemented in Lemmy. It could be, but it’d only work for accounts on the same server. It’d also be pretty easy to detect, although the same also goes for other places that do effectively use shadow banning to fight trolls and bots. The people shadow banning works against aren’t smart enough to verify that they haven’t been caught in the first place.

Nope. The protocol is way too public for shadowbanning.
You can be banned by other instances than your home instance, when that happens no new post/comment from you will federate to that instance in particular but the others still sees it as normal.

Yep the closest you will get is a server will fail to reach out to another server because of a technical issue. But the very nature of activityhub means that it will likely reach out again.
