Build your own trust list. Use DefaultTrust for a little bit. As you interact with the community, find the people you think are trustworthy and build your own trust lists. As you do that, also build your own ignore list. You can start with DannyHamilton's list here: https://bitcointalk.org/index.php?topic=973843.0. It includes pretty much everyone that wears a sig ad (which unfortunately includes me) since most people with sig ads will spam. As you interact with the community, build your own ignore list.
