I'll bump this since it would be useful to be read by more people and I also come with something potentially interesting.
It's only partly related to flags - it's more related to the red warning - , but it's a behavior of the forum that may be good to be known.
I mean this:
Logged-out users will now see a warning in trust-enabled sections if more DT members neg-trust the topic starter than positive-trust him.
This increases the responsibility of DT members not to give negative trust for stupid reasons, but only for things that cause you to believe that the person is a scammer.
And for a better context I'll add
this topic.
