Fair enough. I guess we can skip the other options then, at least for your case. The replacement isn't very thoughtful. For technical reasons, you can't have it your way either. A platform with tree-style comments or replies can't have a comment in-between deleted entirely, or the rest of the tree will collapse. So there needs to be some empty placeholder. Or you just can't use platforms which allow users to reply to each other, but that's more a you-problem. I agree though, if you delete it, it can't have your username or content or timestamp left behind.
