Pop star Sky Ferreira has urged fans to report abuse on social networking websites after she was bombarded with vile messages.

The singer posted a lengthy update on Facebook.com on Wednesday (05Mar14) explaining how she has been the target of a harassment campaign on the site.

She has now called on anyone dealing with similar abuse to reach out to Facebook bosses to ensure online trolls are blocked from contacting them.

The 21 year old writes, "I'm exhausted of (more than some) people telling me how I should look or be if I want to be a 'pop star' & how they think it's okay to say vile & (sexually) abusive s**t to me on a daily basis over the internet. I'm not only writing about myself...because almost every person has to deal with this. It's a shame because I now feel like I can't connect or directly speak with true fans. I'm not a mess, I'm not a drug addict, I'm not a s**t or a b**ch.

"Treating people like s**t because you feel like s**t doesn't help anyone. If you see hateful/disgusting/abusive comments, please start reporting it or deleting it. I think that's the only way we can start to lower that sort of thing from happening. Use the internet as a way to connect with others & learn. Show & spread compassion."
