Hosting an online community raises numerous legal and regulatory challenges. Are you, as the community host, legally responsible for content submitted or shared by your members? This content may infringe other people’s intellectual property rights; might be defamatory; or could amount to some form of criminal activity. But do you know your responsibilities in relation to these types of content and activity, and how do you ensure you protect yourself by taking advantage of the legal defences available to avoid liability? And what about Data Privacy? European Data Protection Laws are changing dramatically over the next 2 years. Collection and exploitation of personal data may be a significant asset and driver for establishing our community. And in any event trust, privacy by design and regulatory compliance should be at the heart of your strategy. These issues, along with key Marketing Regulations and understanding your relationship with and responsibilities to third parties - such as Facebook and YouTube, or your hosting provider, will be summarised.
