Shadowbanning is a good albeit misused resource. Ideally it should be only used against automated systems, such as spammers or karma farming bots. And it certainly should not be made illegal (also, remember that “unethical” isn’t necessarily “should be illegal”).
The problem that you’re noticing is elsewhere: Reddit doesn’t really care about its users or fairness, so it sees no problem on using automated systems to ban users, without manual review. (It’s basically “you’re a user so we assume that you’re shit anyway”.) That is bound to create false positives, and if the system handles shadowbanning it’ll do it towards genuine users too, not just bots.
