Could you as well have a look at my solution regarding UserAuthority (UA)? I've written two very detailed and well-recieved articles about it and have begun developing the code as well together with @stoodkev --> https://github.com/realScipio-ua-js

You could also embed it / implement it to freezepeach, for detecting / identifying malicious flagging:

• UA detects valid users being attacked for no reason (the user has a high-UA)
• UA detects bots attacking valid users (the bot-swarm collectively has a very low UA)
