Is it?

Soft delete is really only a viable option if you're the provider. If you're Patreon and you get a court order with your name on it mandating that you take some content offline but preserve it for the legal proceedings, you soft delete it and you're all set.

But if you're a user of Patreon, you can't know for sure that if you hit the delete button, it's actually a soft delete on Patreon's end, or how long it will stay soft before it actually gets permanently deleted. You also don't generally have a way to access it down the road other than reaching out to the vendor's support staff.
