Ah, I was so fixated on the "pasta" joke, you're right, I missed the other thing! Yeah, I can understand you missing that auto scroll feature.
From what I can tell, it doesn't come as easily as it should natively across all applications, although it appears Firefox has this functionality built in. I found a forum post here from not too long ago. Does this help in your case? :)

Edit:
And here, some folks are discussing a scripty way to do it system-wide. YMMV it sounds like, and I'm honestly surprised this isn't just a tick-box feature by now.
I think they're going through some growing pains is all.
There was that little fiasco a while back where "giveaway" items didn't include lifetime support (understandably) and they didn't denote this clearly, and their standards with participating creators could have been a little better too, which resulted in a lot of items getting review-bombed like crazy.
I admit I even did this to one product because it was actually removed from my account before I had a chance to download it, because the promotion was over. They since fixed that though.
People also do dumb things that hurt everyone involved, like leave 1-star reviews that are essentially customer support questions. "Would not work." Or something.
I dunno, if it were ArtStation or something I'd probably be like "Yeah they're being fishy!"
But the CGCookie / Autotroph / Superhive people are good folk, and I don't think anybody's getting filthy rich off Superhive. Could be wrong, but I'd love to hear what they have to say about it before assuming deceptive behavior.
