The bot hasn't gotten it wrong. People need to learn that plagiarism isn't acceptable here, and there are repercussions for their actions. Nobody gets "banned" by this bot without a warning. They were warned and clearly refused to correct the behavior.
Actually if you look at these cases it was people posting their own content. In one case it seems there was confusion about who owned the account (it was apparently purchased from a scammer) not the content was always original and belonging to the poster.
There is also a difference between a cheetah message and being on cheetah's ban list. The message doesn't come along with flags, and it doesn't necessarily mean plagiarism.
