Your best bet is to make sure you are providing a source on anything you repost from your website. Identify yourself as the original creator of the content, and reply to any of Cheetah-bot's comments by stating you are the original writer of said content.

Cheetah looks at new users very closely, so if you are re-posting your own content, make sure you mention it in the body text of your material here. It may not stop Cheetah from flagging you, but it will serve to identify it to the human readers who see your piece.

Steemit has a huge problem with plagiarism and people who post other people's work without crediting them. Cheetah was created to fight this, but it's imperfect. I've been flagged for re-posting my reviews here that were previously posted to Goodreads, for example. Once you prove yourself to be creating new content, or at least re-posting stuff that belongs to you, Cheetah will probably leave you alone. :)
