There are a lot of issues with everything you've said.
Cheetah can be re-enabled through the DHF but alone it can't catch the offenders and it gives false positives. It's still a machine. Even if we develop her to learn she will never be more than an assistant. I don't want to write an essay here on this but if I get some time I'll put up a post.
Blocktrades is an exchange and a development team. I can tell you right now that they don't have the capacity to sit there verifying Hive users. And even if some company wanted to do it, it's nearly impossible to detect ID scammers on a case by case basis. Detection is only possible while looking at patterns.
The bottom line is any anti-abuse solution should have empathy towards people and treat people irrespective of their origin the same way. This is why HW works, because it must stay to a scope and the process is the same for everyone. The effects of "community pressure" (to ban disliked or unban liked users) have been abolished years ago.
You should get on Openhive Chat or Discord once in a while and talk.
