What you dismiss as "talking about myself or other people for not reading you town" is a pretty accurate way of solving. No, I'm getting people who comment on my wagon to explain their perspective to prevent people just being able to join it without faking a thought process that's coherent. You don't just have to find scum by what they're saying about other slots - as town I have the answers to mine so I'm best positioned to see who is positioning themselves around it. That's the goal here, and it's not just people who scum read me - I've questioned Magic and Aurelian on their town reads of me.
So with that in mind, that there is an actual point to this, you're going to have to explain how I haven't been proactive this game. In actual concrete terms, not the vague terms you guys usually like to use.
