Referrals ONLY need to do what they were asked to do in the beggining of referral bounty program. And nothing more.
ALL other things asked = cheating on people, who participated in wcx promotion
If your referrals don't verify they are real people, they are not useful. Why do you deserve XT, which is a limited supply token and which is already being over bought beyond the maximum cap, if you didn't refer real people?
