Hi, will be fair if my brother register under my link as referral and my father as his referral and sister as father referral? will be that ok or?
I wouldn't advise that if all live in the same household.
Also the system is able to catch abusers that try to refer multiple accounts under the pretense of my dad, mom, relative, pets.
Yeah, emailing me a load of selfies of your family holding their ID cards or passports isn't going to fool our newly improved anti-fraud systems. They will know if the same person was using all the accounts.
