the problem for developers to use the same hash for everyone is the followup of the referred members.

let me explain in real life condition:

A member take the link from the invitations app and publish it in a whatsapp group of 100 people:
as I see every new member will be registered and befriended normally, they will get their points.
but at the end the icode will be associated only with the latest user that comes from that referral. here we lose the ability to follow up the referred users.

this is important because we will need to see (or show the refferring user) who came from his/her referral.

may be in futere updates a minor modification will be benefical to overcome this problem.
