'Sued by my abuser for millions, I set up a social network instead'

Olivia DeRamus was 19 and studying at university in California when she was sexually assaulted. The situation was made worse when she found she couldn't speak out about it.

"I was sexually assaulted. And my story doesn't end there," says Olivia.

After reporting the incident, the university launched an investigation and took action against the alleged perpetrator.

Olivia chose not to go to the police to avoid more trauma. But she still found she was caught up in a legal battle that lasted for years.

"I was actually sued by the perpetrator of my assault, for defamation."
