> We estimate that the average of false or spam accounts during the fourth quarter of 2021 continued to represent fewer than 5% of our mDAU during the quarter. However, this estimate is based on an internal review of a sample of accounts and we apply significant judgment in making this determination. As such, our estimation of false or spam accounts may not accurately represent the actual number of such accounts, and the actual number of false or spam accounts could be higher than we have currently estimated.

Not a native English speaker so maybe I'm just not understanding it correctly.
Since mDAU are a subset of DAU, probably a tiny subset of it, wouldn't that statement mean that way way less than 5% of DAU would be bots?
No. That statement is the fraction of mDAU accounts that are false/spam.
In a situation like this there is a very strong implication that you're talking about the intersection of the sets 'bots' and 'mDAU'. To talk about the raw number of bots vs. the raw number of mDAU would require very explicit wording to override that implication.
