You are welcome! I have seen steemcleaners abuse their position before and never apologise for anything. Steem cleaners is not any kind of official bot or service from steemit inc. - it is just an account run by people in the community from their own initiative. I have forwarded your post to a witness group for their notification.
To my knowledge, 'cheetah' can be prevented from being triggered by pasting a URL to the source page for whatever you copy/paste into steemit. Stopping steem cleaners is a bit more tricky though.
