Well the intention was people who have sent seeds already have a history/track record of delivering on their word.
Therefore in a trading scenario, the less known/newer member would send beans first and upon their being received by trusted member, she/he would then send out to the new member. This means we dont need to wait for “pips”.
If someone is “trusted” on this list they have proven their trustworthiness to a lessor or greater degree. (somewhat signified by the number of times they are mentioned)
The fact lots of members had a “love fest” for each other early on is less useful but I can understand that people have built trust in more nuanced ways than a simple “deal”
hope that makes sense.
