Perhaps it's time to discuss the etymology of the term 'troll' as it's used here. The term has much more to do with the fisherman's version of the definition: a lure or net dragged alongside the boat, used to ensnare fish.
So when you think of the term troll, think of someone planting hooks in the juicy meat of the thread just waiting for someone to take a bite. They don't necessarily have to look like warty and disfigured creatures of folklore.
But if you want to think of them as warty and disfigured individuals, I've got no problem with that.
