In February 2011, an incident allegedly prompted by bullying on Formspring led to the death of 15-year-old Natasha MacBryde from Bromsgrove, Worcestershire, United Kingdom. The Coroner's inquiry heard that she received anonymous personal abuse via the website on 13 February; this appears to have compounded bullying and teenage anxiety to a level, where Natasha took her own life on 14 February after researching suicide methods. According to the Daily Telegraph, Det Sgt Shanie Erwin told the inquest that Natasha was known to have received a short anonymous message containing personal abuse via the Formspring networking site on February 13. The message, which was read to the jury by Det Sgt Erwin, derided Natasha for “hiding” behind make-up. It ended: “Start acting nicer to people or you will lose everyone. Mark my words.”<ref>{{cite news|url=http://www.telegraph.co.uk/technology/social-media/8653867/Teenager-in-rail-suicide-was-sent-abusive-message-on-social-networking-site.html |title=Teenager in rail suicide was sent abusive message on social networking site |publisher=Daily Telegraph |date=2011-07-22 |accessdate=2011-09-16 |___location=London}}</ref><ref>{{cite web|url=http://www.birminghammail.net/2011/07/22/beautiful-and-talented-teenager-took-her-own-life-inquest-97319-29097736 |title='Beautiful & talented' teenager took her own life - inquest |publisher=birminghammail.net |date=2011-07-22 |accessdate=2011-07-25}}</ref>
