I'm quite upset because youtube has blocked my Loki/Sigyn vid (as they did with my Rorschach tribute), due to copyright issues about the Natalie Walker song. It annoys me because it's so much work lost, and L/S shippers liked that video, it was one of the first L/S videos on the Net. I wonder why we fans can use characters, etc. from a franchise for writing fanfics, or even images of them for making photo manipulations, but we can't use clips of video nor songs for making fanvids? Even in the case of music with copyright, we earn no profit of using it, and we are making people know it. I've known many bands, singers and songs thanks to fanvi
