This article explores the norms that govern regular users’ acts of sharing content on social networking sites. Many debates on how to counteract misinformation on Social Networking Sites focus on the epistemic norms of testimony, implicitly assuming that the users’ acts of sharing should fall under the same norms as those for posting original content. I challenge this assumption by proposing a non-epistemic interpretation of (mis) information sharing on social networking sites which I construe as infrastructures for forms of life found online. Misinformation sharing belongs more in the realm of rumour spreading and gossiping rather than in the information-giving language games. However, the norms for sharing cannot be fixed in advance, as these emerge at the interaction between the platforms’ explicit rules, local norms established by user practices, and a meta-norm of sociality. This unpredictability does not leave us with a normative void as an important user responsibility still remains, namely that of making the context of the sharing gesture explicit. If users will clarify how their gestures of sharing are meant to be interpreted by others, they will implicitly assume responsibility for possible misunderstandings based on omissions, and the harms of shared misinformation can be diminished.

本文探讨了规范常规用户在社交网站上共享内容的行为的规范。关于如何消除社交网站上的错误信息的许多争论都集中在认知的证词规范上，隐含地假设用户的共享行为应与发布原始内容的行为属于同一规范。我通过对社交网站上的（mis）信息共享提出非流行性的解释来挑战这一假设，我将其解释为在线生活形式的基础设施。错误信息共享更多地是在谣言传播和闲聊领域，而不是在提供信息的语言游戏中。但是，共享规范无法预先确定，因为这些规范出现在平台明确规则之间的相互作用中，由用户习惯建立的本地规范，以及社交性的元规范。这种不可预测性并没有给我们带来规范上的空白，因为仍然存在重要的用户责任，即使共享手势的上下文明确的责任。如果用户阐明他们的共享手势是如何被他人解释的，则他们将基于疏忽对可能的误解承担责任，并且可以减少共享的错误信息的危害。
