What Cheetah and steemcleaners are trying to do is to stop scammers actually.

There have been many people who have come on Steemit and post other people's content, claiming it as their own.
They get votes for somebody else's work.
This is probably considered the biggest taboo here on Steemit.
What people post here is supposed to be their own content.
Of course we may quote other people's content,
as long as you add your own thoughts to it and acknowledge that the quoted part isn't your own.

Cheetah is a bot,
so it can't tell your intentions.
So that is why it doesn't flag people, but rather upvotes them and leaves a comment behind to let people know that it found material that is already elsewhere on the web.

I'm sorry that you have been bothered by this, and misunderstood it.

If you follow my original suggestions,
and clearly acknowledge through the proper tools that you are quoting someone,
you should have no problem.

I wish you the best here on Steemit.
