论文摘要
默认情况下，Twitter帐户是公开的，但是Twitter提供了创建受保护帐户的选项，只有批准的关注者才能看到他们的推文。公开可见的信息基于帐户类型和推文的可见性也仅取决于海报的帐户类型，这可能会导致意外披露，尤其是在用户互动时。我们调查了336个Twitter用户，以了解用户对帐户信息可见性的认识以及用户互动时的推文可见性。我们发现我们的参与者知道他们的个人资料信息和个人推文的可见性。但是，遵循主题，列表以及与受保护帐户的互动的可见性令人困惑。只有31％的参与者意识到，公共帐户对受保护帐户的推文的答复将是公开可见的。令人惊讶的是，拥有受保护的帐户不会更好地了解帐户信息或推文可见性。
Twitter accounts are public by default, but Twitter gives the option to create protected accounts, where only approved followers can see their tweets. The publicly visible information changes based on the account type and the visibility of tweets also depends solely on the poster's account type which can cause unintended disclosures especially when users interact. We surveyed 336 Twitter users to understand users' awareness of account information visibility, as well as the tweet visibility when users interact. We find that our participants are aware of the visibility of their profile information and individual tweets. However, the visibility of followed topics, lists, and interactions with protected accounts is confusing. Only 31% of the participants were aware that a reply by a public account to a protected account's tweet would be publicly visible. Surprisingly, having a protected account does not result in a better understanding of the account information or tweet visibility.
