It is all unnecessary cause no one should be actively trying to build reputation. If you are offering a service and want to show you are trustworthy that is fine, but trying to get good feed-backs by taking out loans or engaging in other activities to farm trust is wrong.
I seriously didn't wanna talk about this but, as duely observed, I'd like to ask ; do we really have people taking out loans and paying back huge returns just to farm positive feedbacks? Some of which may not even be achieved at the end? I think I understand everything now.
