I've seen a lot of real popular and reputable web hosts brag about paying out $90 or even $115 per referral for customers paying like $3.50/month. How could that possibly be profitable to the hosting company? What's the catch here? I'm well aware of sites like 000webhost and etc screwing over top referrers, but those are kind of off-brand hosts if you will. I'm talking about the major competitors like HostGator and iPage, ya know, the places where it's real easy to get ahold of customer support people.
