Stop the domain hide / steal content? !

Agree – I recently discovered that some websites simply masked our domain with theirs or used rss to extract content – or maybe a third party robot.

Therefore,
We have disabled on-site RSS generation
Install a jar of honey in case a robot enters
Configure Wordfence to allow only the crawling of a verified Google bot.

Problem
The moocher site in question is still able to steal content in real time – how to identify and block such a leech?
I will post links if necessary – or if someone can give an overview of that.
