Nobody force you to register with GoDaddy, and knowing this facts, you shouldn't.

But this still does not change the fact that IF GD gives the biggest $ for referrals, then that make sense for OP to integrate it, especially since he is not charging anything for this service and he made it on his spare time -- so I don't see the problem with this.

There’s always more to consider than just $/referral. For example blinking, pop-up ads might be more lucrative in the short term, but in the long term could turn to be too annoying, and end up putting off some users. The choice of monetization opportunities says a lot about the character and priorities a company has.

Like I said, I don’t want to take sides and start a flame war here, but it’s a fact that dealing with GoDaddy is controversial, and no company operates in void — your choice of registrar or ad network has certain implications, that ought to be considered.
