A troll that makes fake posts in order to get people to read with their fantasies and feed their fetishes. This type of troll gets off on comments that acknowledge and interact with their fetish fantasies.
You can usually tell a post is fake and written by a fetish troll when the post has too many unnecessary details and the details are related to some sort of fetish. They usually ask for “advice” at the end in order to get people to interact with their fake posts.
“Wow! A guy in this violin lovers facebook group made a post saying his violin teacher spanks him with his violin bow for making mistakes! He’s saying he constantly feels sore and wants advice.”
“Ugh, that’s just a fetish troll. Don’t feed his fantasies.”
