I think these sorts of cases will be very rare, but they will probably work themselves out. As vod said, exclusions can be made for people who are no longer active
Not everyone is going to revise their trust list which we are seeing from Zepher's case.
Over time they likely will and it's not been that long in Zepher's case, but there's also the debate of should feedback from trusted users be excluded because they're no longer active or have died? Imagine if you have a lot of feedback from users who have left the forum for whatever reasons. You could go from being pretty trusted to having little no feedback. You could make the argument that any active member would continue to get feedback from others but not always, especially if you don't do that many trades as you used to and that's why admin intervention may be better in certain cases to remove a specific feedback that's causing an issue, but maybe theymos still doesn't want to get involved in that.
How about this?
- You must have posted sometime within the last 30 days.
It's one of the criteria of DT1 selection. Theymos can use something like this for someone being in DT2 too. Point is if someone is not active for certain amount of time then despite being in the trust list of DT1, the user will lose their DT2 status.
This way their feedback will not reflect as trusted anymore unless they fill up the criteria again.
Maybe make the DT2 one with a longer duration. 30 days is ok for DT1 but 30 days for DT2 would seem a little short in my opinion. It's probably not that uncommon for less active users to leave the forum for a month or so.
