True, we're basically both talking about a tagging system, they can be parts of the same system. But I think once we have that system, you'd end up finding it's not worth trusting anyone to label what's spam or bots, it's better to just meet someone face to face to verify you're a human. I also notice the part you're talking about keeps getting built and rebuilt 10 times by scammers and liars while nobody is actually serious about solving the problem enough to build the part I'm talking about one single time anywhere. I'm scared of how many more hundreds of "trust someone to magically keep up with all the bots without mistakes" systems we'll get before we get a single "blame liars for lying about whether they've met someone face to face" system
