You would have to be directly put in the DefaultTrust list by theymos himself to be at depth=1 though
Otherwise you'd be at depth>=2, so your own trusted users would be at depth>=3 in the DefaultTrust list, so people with original settings (DefaultTrust and depth<=2) wouldn't trust those
For newcomers, the trust system is useless for a number of reasons. For one thing it depends on the trust of theymos and many people don't trust him.
