Again, rather than addressing my point that the net detriment is larger than the net gain, you attempt to shift the topic to your demands for proof of "signal noise".
Because I deny the very implication that the net detriment is larger than the net gain, because of the points I have made above. As you have been arguing for this whole time, the burden of proof is on you, as the one making the claims, to prove that your claims are factual and not just your opinions. If red tagging scammers is indeed causing such overwhelming amounts of harm to the forum, then it should be trivial for you to "document it in an objective and observable way". I wonder why you refuse.
Yeah, we noticed. Good for you, you can make a denial. Now try arguing the logic of the other points I made. As usual you aren't willing to have an intellectually honest debate. You zero in on the two words you can hyperfocus on to disregard the entirety of the rest of the argument in order to totally avoid addressing the rest of the content. I am going to just start quoting myself if this is how you insist on engaging with me. You insist that if I can't some how document causality of what happens in the minds of other people, then I must be wrong. You are totally disingenuous. Don't you have some more tires to slash?
I am sure Mao killed lots of bad people that were criminals. No one says, "there are examples of him correctly killing people that deserved it", because the problem is all the collateral damage and innocents caught up in it. Again, the question is not if people are correct some times or even most of the time. The question is, is the damage created by allowing such an arbitrary standard worth the minimal amount of impact the "correct" ratings have? I don't think so.
People who aren't doing this basic level of due diligence are just on borrowed time until they are robbed and no amount of shitting out tags is going to stop them from getting stolen from. Also doing so creates a false sense of security that the forum is moderated protected against such things. Then there are the people who use it to punish people bringing their own crimes to light and to discredit those accusations. Also the negative rating spam effectively dilutes the value of leaving a negative, because it is so common people learn to disregard it. All this ends up being is signal noise. Signal noise actual con artists can manipulate to cover their tracks and punish their detractors.
As far as your car analogy, it is not an honest one. You compare your position to putting on a seat belt vs not because some people drive recklessly. A more appropriate analogy would be people running around and slashing the tires of anyone they think is driving recklessly. Sure, maybe it might keep some reckless drivers off the road temporarily, but they can quickly just get new tires, and now we have to live in a culture where it is ok for people to run around slashing tires as long as they can make up some lofty pretext to justify it. What could go wrong there?
