It was not pretty. Two of my friends (and a third person who has become a new friend through this) were sent tumblr asks (the de facto messaging system of tumblr) from some anonymous person saying they're sick for shipping Spuffy, they should be raped, killed, etc. one person was at work and came home to these messages, one tried to reason with the person and only got grief, and one person has completely withdrawn from fandom because of this.
