Summary: After a UK teen took her own life in response to bullying on social networking site, ask.fm, her father asked both the site and the UK government to take corrective measures to prevent further tragedies. This wasn't an isolated incident. Reports linked multiple suicides to bullying on the teen-centered site.

Ask.fm's problems with bullying and other abuse appeared to be far greater than those observed on other social media sites. Part of this appeared to be due to the site's user base, which was much younger than more-established social media platforms. This -- combined with the option to create anonymous accounts -- seemed to have made ask.fm a destination for abusive users. What moderation existed before these problems became headline news was apparently ineffective, resulting in a steady stream of horrific stories until the site began to make serious efforts to curb a problem now too big to ignore.
