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.
So by DT members, did he mean only DT1 or DT2 as well? I always tend to think DT members is general (DT1 and DT2)
Take
this user for example. He has negative feedback from 3 DT2 members and when you check some of the topics he opened, the banner with a warning does not show up.
