Trust come from reputation. There are some legendary members with no reputation within the sphere of project management, bounty management, community management etc. Others may even have negative trust on the forum. I will only trust a legendary member who announces a project if the member meets all of the above.
so true. even if they are full members, or below, I don't think it has any effect. what affects is the reputation and the results of his work so far. however, there are many legendaries, or accounts that have a high level but do not have trust in other members when they open a project.
