There are bots which report things all over Steemit. Some identify if a post has been Tweeted for example. Others indicate if a post has been linked elsewhere in Steemit.
These are useful tools as are tools which identify that source content came from somewhere inside or outside Steemit.
@cheetah is a scout. Nothing more, nothing less. It's not a mark for or against any given content. It's a presenter of usually factual information. You claim it should be fixed. If it's presenting something false that would require fixing. If it presents a clear link to content which exists elsewhere what needs fixing?
In regards to the name it may have been a clever name chosen by @anyx
What I know about the project is the bot used to call out content as "possible plagiarism". As you can clearly see the bot now only states that something is available elsewhere. It doesn't accuse that there's no citation. I believe Cheetah is a fine name because it indicates speed and efficiency. It also indicated being a predator which I believe has been toned down in practice.
The language you use indicates your own bias in this matter. You claim the bot "marks" a post by adding a comment. You claim users and posts are being "hit".
I'm writing a comment right now and I'm neither "marking" nor "hitting" your post. Why is @cheetah any different?
To mark or hit would indicate flags. So far I haven't seen flags issued which weren't warranted. Your calls to flag @cheetah in my mind warrant a flag.
Several times already you've admitted you don't know or understand the system. @cheetah and @anyx have several posts introducing and describing the bot. I have no qualm if you choose not to educate yourself. I have a huge problem with you advocating action and making broad assumptions about something you never took even the slightest time to learn about. You're arguing from ignorance. You've admitted so. It's definitely a strike against your credibility.
P.S. Read some of the things you linked to. @anyx called the problem with @cheetah "fickle" not the user. Even indicated they wouldn't receive another comment from @cheetah in the future. Please read more carefully and you might see that steps are made to improve the bot.
