3. Cloppers
Despite Rule 34 of the internet (If it exists, there is porn of it), there are many things that, luckily, you will never find pornographic fanart of. I'm sad to say that My Little Pony: Friendship Is Magic is not one of those things. I'd like to start by making the point that Bronies (fans of My Little Pony) are not bad people. I'm friends with several Bronies and they are all friendly and well adjusted people who just happen to be fans of a cartoon about magic ponies. But on the other hand there are the Cloppers, the disturbing lovers of pornographic My Little Pony artwork and fanfiction that give Bronies everywhere a bad name. Much like how a lot of people think that all Furries are Yiffers (the distinct minority of people whose interest in the furry fandom is sexual), any Friendship Is Magic fans that aren't pre-teen girls are automatically assumed to be your standard basement-dwelling weirdos, an image problem that isn't helped by the Cloppers. This
Tumblr account contains a number of stories about how some Friendship Is Magic fans left the fandom because of Cloppers overrunning forums with My Little Pony porn, with some developing a persecution complex and others claiming that they are more devoted than the average fan because they spend their free time drawing pornographic images of cartoon ponies. If you masturbate to cartoon ponies and think that it somehow makes you superior to those who don't, then you are in serious need of some form of psychiatric treatment. And don't even get me started on the person who spent $1025 on a fan-drawn My Little Pony porn comic called Hoof Beat. Being a Brony comes with a stigma. It's a strong possibility that, no matter how intelligent and successful you are, you'll get pigeonholed as somebody with some kind of personality disorder simply because My Little Pony is perceived as something that only children should like. And the kind of perverts that create and share pornographic fanart are not helping that image problem.
