Do you think an additional indicator of “meta game level” or “zero trust level” for each activity would be helpful?
Basically that new indicator would help determine how much (relatively) trust to other players is required to perform the activity successfully 
I will try to explain what I mean by “meta game level” or “zero trust level” on below examples:
High level would be any element that is arranged by players with the help of tools outside of main game mechanics and not fully supported by it as an implemented UI options.
Example would be “Mercenary Contracts”. There is no such thing supported by game mechanics (yet) players simply communicate their intent and interact based solely on trust to each other in regards of payment and collateral and job done.
Low level would be any element that is specifically integrated into game mechanics and fully supported by UI options. Example would be “Courier Contracts”. Fully supported by game mechanics and players simply use specific UI options to setup contract and secure payment and collateral. Little trust is required from both parties, although it is not scam-proof obviously.
More on this element of EVE in my forum post.
This is the hardest part to grasp in any mmo game imho but very interesting to study and helpful to enjoy the game …without regrets
