Thanks for your comment @sandrina.life! You're right, there is a lot of rubbish here, so I'm glad to hear you're keeping your eyes open!

Cheetah doesn't know who's the author of any content, so she comments on copies from your own website too. In that case, you can just reply to her, saying it's your own content. I always post that below the article aswell. Even better is if you post a link to your Steemit account on your website, so it can be verified that it's your own site :-)
