Parag Agrawal: 我们的估计是基于对数千个账户的多次人工评论（重复），这些评论是随机抽样的，随着时间的推移，从我们算作 mDAU 的账户中始终如一。我们每个季度都这样做，而且我们已经这样做了很多年。

原推：Our estimate is based on multiple human reviews (in replicate) of thousands of accounts, that are sampled at random, consistently over time, from *accounts we count as mDAUs*. We do this every quarter, and we have been doing this for many years.
