Parag Agrawal: 现在，我们知道我们在捕获垃圾邮件方面并不完美。所以这就是为什么在我上面谈到的所有垃圾邮件删除之后，我们知道有些仍然漏掉了。我们在内部对此进行测量。每个季度，我们估计该季度报告的 mDAU 中不到 5% 是垃圾邮件帐户。

原推：Now, we know we aren’t perfect at catching spam. And so this is why, after all the spam removal I talked about above, we know some still slips through. We measure this internally. And every quarter, we have estimated that <5% of reported mDAU for the quarter are spam accounts.
