This thread is just for discussion. No need to get your tits in a knot over it if you take the trust system so seriously that it effects your sleep. It's not a suggestion for change, just a poll and discussion.
It's been discussed many times. Anyone can use trust feedback any way they see fit, including red-tagging for lying, but sane users would likely exclude you if you tag someone for lying in a non-trade-related discussion. Someone saying that Santa exists or that Earth is 6000 years old is not necessarily a potential scammer.
