I agree that fraudulently reporting false canonicals is 100% unethical and should stop immediately.
That means you: 
You are actively committing fraud by representing your site as the original publisher of other works.
STEEM as a blockchain is tricky since the source of the data is a publicly available blockchain. That is why proper canonical references are important to let the world know where the content was initially created and submitted.
If this isn't fixed, users will have to start using DMCA and GDPR legal tools.
