I understand it the way Primus claimed he meant it. He waited for you to confirm it.
I am not sure it is against the rules to request positive feedack.
I got a very similar message to OP and am rather willing to fund this loan as I find this matter quite confusing.
However, it may look like farming if he is asking for positive trust.
It is up to users to interpret requests for positive feedback.
Sometimes the request is subtle (I have left you positive trust....), sometimes it is not.
