I looked at your list and there are a lot of distrusts, even on level one.
Note that those aren't my own direct choices: I only distrust 9 users (
explained here), but on Depth 1 I distrust 175 users through the users I trust on Depth 0.
I also noticed there are a lot of people with zero merit and it may be a good idea to investigate if you want these people in your trust network and why they are in your trust network and if you want the people including these people in your trust network.
I looked at a few, and they're older accounts, some of them inactive, included by older accounts (now DT1) years ago. I see no reason to exclude them, but I will if a reason pops up.
I am not sure how difficult this would be, however it might be useful to include trust ratings either via DT or via a custom trust list. The rating could be as of a certain point in time so that your VPS (I presume) is not consistently scraping the same information.
I can't scrape trust ratings, it needs an account to be logged in. I could get it from Vod's
BPIP, it's actually not that bad to scrape 10,000 accounts per week and add the rating to the "Trust feedback" link text. It will still be slightly delayed that way. I like it!
I'm still not using a VPS, just old fashioned data uploads

This makes a great argument for setting your depth to no more than 1 if you have a custom trust list. Even on depth 1, there are a few names I am unfamiliar with and have had no interaction with
What I would really want, is to have DefaultTrust up to Depth 2, and my own Trust list up to Depth 1. Unfortunately, that's not possible.
by level 2, a quick scan and I would estimate around 75% of names are users I do not know, including many who have been inactive for months or even years and a fair few who are red trusted themselves.
So the users you trust are trusting users who trust the wrong users

Let me highlight the "large recursive implications" in the OP

The red trust would be a good reason to add QuickSeller's suggestion to my list. I've sent Vod a PM asking if I can do weekly scraping from BPIP.
