Funny thing dat... there are goblins in the game, yet no one has gotten around to really putting them in game. Only one you see is Colenso, so really Rasks aren't goblins... except for being fuck and breed happy which I can understand is where the confusion would come from. The term "fuck like rabbits" can be applied to them though
It's a conspiracy, I tell you! We'll get to the bottom of this, me and my bro Colenso. Truth is out there somewhere.
