I really not sure what you said, but Cheetah is run by SteemCleaners, and if they have proof someone owns a third party site they can whitelist the site for them.
Cheetah is not smart, it's got one job. Find duplicate content. While 99% of the time it is the result of plagiarism, sometimes it is not. It takes a human to make that decision.
Yes I also said same things..
that cheetah is down voter. and can down vote if one violate the steemit rules like copy pasting from third party site...
