I had an idea for a premise of a story, but I'm not going to write it if there is a similar one. It would feature an online "troll" who metamorphoses into a literal ugly troll from Norse mythology/folklore due to a sentient online curse. I know that (awful?) movie Beastly is about this (and, of course, the novel on which it's based) is sort of like that, and curses like this are common in dark and/or romantic fantasy (there would be no romance in my story), but has it ever involved trolls in particular, to your knowledge?
