Why is spam score always weighted as a single outcome and never as a population-based result? I mean, you’re processing more data, I get it, but it feels like that would be a model much more resilient to tampering, bad actors, and just different social norms. For example, if one set of users started rating a specific subset of posts as spam, then those users could be bucketed together into a “doesn’t want to see message type A” group while others, who minded other messages, would be bucketed into a “No B-messages” group. This would need to be applied selectively, as it could easily result in an echo chamber for normal discourse, but I would’ve given my left arm to have that sort of filtering available in the game during my WoW days. Those city spammers were unbearable! I, of course, would have fallen into the “I don’t care how great a deal your Thunderfury, Blessed Blade of the Windseeker, is, I’m just here to socialize” bucket.
