Trusting someone is not reason enough to add them to the trust list (despite the name).
We must add people to the trust list if we think the feedback left by those users is useful and fair. And it must be useful for most if we're DT1.
If someone is extremely trustworthy then they must have dark green trust but not necessarily be on other people's trust list, unless they also leave proper, useful feedback.
You can write that in public another 10 000 times, it's pointless. How many people did you PM about it and how many did listen to you? Here's a hint: They won't remove the inclusions because "friends". Circular ad naseum won't get us anywhere; either theymos changes it up a bit or very strong trust will remain a reason for inclusion for many.
I'm sure there are people who honestly don't know the difference, so posting it does help. I've PM'd dabs and will exclude him if he doesn't fix his list. I hope others do too.
But I agree theymos must change something, either requiring more than one DT1 inclusion to make someone DT2, or ignoring inclusions made by X when calculating X's trust. He should also make sure at least DT1 users know how things work, either by adding clearer messages next to the trust list or by PM'ing every DT1 users as soon as they become DT1.
