Amateur content created/posted by obsessive fans that impedes the ability of the average user to access original content on audio/video streaming sites such as Youtube etc. This material usually features unwanted content such as home videos of individuals singing their versions of songs, shitty remixes, or clips of various anime movies with the song playing in the background. When an average user tries to find a song/video they are partial to, they often come across 100+ fanspam videos before they can actually find the real video.
"WTF.. I'm trying to find that song by Depeche Mode. What is the title of the track? Taking a Ride with my Best Friend? I can only find shitty fanspam videos with crap mixes and anime videos. WTF is this shite?"
