Referrals

what are they

Theory 1: Referrals are useless
never heard of 'em before, so they must be useless.

Theory 2: Referrals are the number of times someone sent furycoins to another user
gotta keep track of those coins, right?

Theory 3: Referrals are done and gone
seems to be the most likely option if you ask me. they belong to the past, like other forgotten features.
