The first example used to work pre-UCP when anonymous users had a Message Wall and can still be used for registered users. It's what I've used in the past and is the same as what HCWE suggested, but by putting it in the block reason, the anonymous user will see it if they come back under the same IP and the "you can't edit because you're currently blocked" notice appears on the page.

It gives them a chance to see why what they did was wrong and gives them the opportunity to change their behavior so it won't happen again. Whether they actually read it or try to change their behavior is a separate matter, but at least the admin can show they tried to communicate with the anonymous user because it isn't as straightforward as it used to be.
