The byteball team's idea to airdrop to steemians with rep higher than 30 is amazing in my opinion.
It's sad that people in a way make use of other people's work and steal the referral bonuses though.
But I guess in life there's always someone trying to game the system.
The rep should have been 50+ to be honest, and the referral system should have been rock solid and not so easily exploitable.
I'm not so big on stake-anything, but the fact that the rewards were tiered by rep and not stake just made the whole thing seem scammy to me.
