I've earned over $8,700 in commissions from GDI, mostly from 2007-2008.. I promoted them through some marketing systems. Most of that income actually came from bonuses, you get $100 for every 5 referrals you get in a week and I was on the leaderboards every week. In the end, though, even with nearly 300 in my downline.. I would only make $300/month residual because out of the $10/month that they paid for their membership you get 10%... $1 per person in your downline. So if you want to earn $1,000/month passively you'd need 1,000 people in your downline, and not everyone is staying as people left pretty heavily too. I have only a handful of people left in my downline (I haven't promoted it for many years), and the only reason I keep my membership is because that downline is covering my cost of membership.
I decided it was not worth my effort to promote for such a low payout. I think they changed some things now with some new memberships or something, but I don't understand the $10/month for a domain when you can get one for that much per year somewhere else.. I guess the benefit is their sitebuilder, but then that is just for people who have no technical knowledge about websites at all.
