I used to have Nelly Furtado's Man-eater video (from youtube) posted on my account, then 2 days ago I added Nelly F to my friends, and now the video is gone. I went to the link I posted here a few days ago showing the video and it says "This video has been removed at the request of copyright owner the RIAA because its content was used without permission". Does that mean Nelly reported my page?

In fact everything from my page was deleted. I had to make another layout, contact table and where I went to school.

yep, you must have the authorization of the artist, most of the videos posted in MySpace are from Youtube and are stupid things or independent/unsigned artists.
Insted of using youtube's video, use MySpace's videos (if the video you want is available)

And that probably means that one of the Myspace peeps saw it and reported you. I personally don't think the artists really make their myspace. I think their label makes it because would the artist really say:

"Nelly Furtado performing Tuesday at blah-blah"

No, I would think:

"Hey guys, I have a performance coming up Tuesday, if you're near blah-blah, come check it out. Bye!!"

You shouldn't hate her if it happened, its not US so yeah.

I really don't think so. I think that the person who posted it on youtube was reported. Just like when the ANOM video was on youtube like a day early RCA had all the videos taken down. If anyone is going to be in trouble it's the people from youtube not you. I also don't think that it's that serious. When the people over at LD posted the B2b preview clips, RCA/Sony Music politely told them to take it down.

Ok, thanks for the info.
