Hi, strange000, thanks for your question. We have checked the friends refer point system, and found some error which disabled the system to give referral points. We are going to fix it as soon as possible. We do apologize for this, and if you have other questions, please feel free to ask, thanks.
That's a good question and I have wondered that myself. The same thing has happened to me. I hope someone can solve this.
I would assume the awarding of those points would be contingent on your friends accepting the invitation and actually joining Blurtit. Otherwise I could refer Blurtit to everyone I know just to get the points.
Maybe it is a glitch, referring people to Blurtit are supposed to let you have points, wait for a while and try again, hope Blurtit sort out this mess.
