Yea. I think that's part of it. I believe you can't delete posts because, once it's on the blockchain, it's locked in. However, I don't see why they can't have a button that essentially deletes it from view. It's still on the blockchain but just hidden from your blog and in any feeds it was in. The content isn't removed from the blockchain. It's simply hidden from view.

That's my thought on how to solve it at least.
