Yeah I get that "did you really want me to join or did you just do it cause you're making money from my activity?".
I'm looking forward to see how it will turn out, I wouldn't be against it if there would be other sort of rewards that wouldn't directly mean you are gaining Steem or monetary rewards for referrals.
Yeah, it's a tough one... I definitely see potential pros and cons, but it could very well be a good thing. I like the idea of "creative rewards."
