Firstly, not everything is "shilling".
Secondly, there actually IS/was one guy, in particular, who spammed the show, periodically for about a year, even leading up to the actual show being launched, but he's an annoyance to everybody, even to the people actually making the show.
Thirdly, it's actually pretty good. It's like a return to simpler roots for a cartoon show, and the designs and effort put into it are nice. And, of course, also, waifus and incest.
