Why did all my stuff in the Justin Bieber spot go away?

i added really cool stuff there. I put some wallpaper my sister make for me. She made them herself, i saw her, so it wasnt already out there. I also put cool picks like What of Justin Bieber's favorite bands is your favorite too
and i also put Would Justin Bieber look cool as a vampire?
and then i also put Whats your favorite cover Justin Bieber did?

nobody ever asked those questions before.

and then I was the first person to put the U Smile video up and then a buch of peopel put it after me and those are all still there. I asked one of my friends i thought was in the Killers why and she told me they might be duplicated or something i asked her what that means and she said its a copy maybe but i looked and none of that stuff was already there.

are people really angry at me for no reason or something and dont want my stuff there?
it makes me really sad that all those people dont like me and i never talked to them or Justin Bieber
