I think the OP is referring to the wording on the Rewards section of the user panel where it says you get referral credit through any one of three methods. The third method is the version with using the "http://www.dreamhost.com/r.cgi?" referral link. The OP is referring to the fact that Dreamhost is now running certain specials on their front page that are better than the "no discount" that one gets from a raw, undiscounted referral. Therefore it is pretty unlikely that someone clicking on a link like the one above would actually sign up without a promo code.
This sounds likely to me.
Of course this is unrelated to people we refer from our own sites at times when Dreamhost isn't running great discounts like they have been for the past couple of weeks.
