Except being morally objectionable and a PR disaster? No serious website would do that. I've completely stopped visiting The Pirate Bay after they put a miner there without users' consent.

The serious use case for these miners is that you have some kind of incentive for your users to mine, not just have it mine randomly in the background. I guess it works for pure donations but take a look at "Use Cases" on the front page for a couple of examples of what I mean.

That makes sense. I do appreciate that they went to the effort of putting intended use cases on their website, and I wouldn't mind explicitly encountering some of them (I would gladly mine some cryptocurrency to help support video creators I enjoy rather than watching or seeing ads). I just worry that "morally objectionable" and "PR disaster" aren't enough to stop JS miners from being used without the user's consent on sites--to me it feels somewhat comparable to ad tracking behavior.
