Guardian article "We will look back at cyber-harassment as a disgrace--if we act now", by Danielle Citron.

Excerpt:

"Whether it is thanks to commercial interests or social responsibility, some online platforms have taken a stand against cyber-harassment. Social media providers, including Facebook, Microsoft, and Twitter, now ban threats, cyber-harassment, and non-consensual pornography....

"Companies should be clear about their policies. They need to explain what they mean by “cyber-harassment”, “non-consensual pornography”, “threats” and “bullying”. Users will then have a better understanding of precisely what is and what is not prohibited. Platforms should explain whether content will be taken down or what the next step would be."
