I count 3890 users with a custom trust list
This is very bad, worse then I thought. DT needs to go, so people can finally start using the trust system as it's intended. Either completely remove DT and start healing trust system slowly, or dilute DT which encourages people to make their own lists.
That list also includes people who have Default Trust included on their trust lists. It is actually a good sign and shows that thousands of people are augmenting DT with their own alterations as advised. I'd disagree with your interpretation and say this is better than I'd thought. I wonder what sort of growth is happening with users augmenting their lists?
