"We estimate that there are 3.5M profiles [95% CIs: 2.9M to 4.1M] conducting Inappropriate Interactions with Children (IICIICInappropriate Interactions with ChildrenA classifier threshold and content category for interactions between adults and children indicative of grooming or exploitation, referred to internally as "a.k.a. 'grooming'".

In percent terms, this is 1.1%." [Assumptions and caveats]: "'Potential Groomers' Review. There are a large amount of accounts marked as 'potential groomers' (18M [16.6M to 19.5M]). In these cases, the reviewer was either unsure of the profile's user age, or there was ambiguity in the conversation. We will be re-submitting the 'potential groomers' to a double review to be extra sure on this number, and it is possible that the IIC numbers could increase with additional review. We have already conducted double review on accounts marked as IIC." "Countries we didn't review. We were only able to review profiles in 22 markets due to labelling resources. This group represents 73% of this population (233M/320M). The above 3.5M number is based on assuming that the countries we did not review have the same rate of IIC activity as the 22 countries we did review. If we do not make this assumption and restrict to the 22 countries we reviewed, our estimate is 2.55M [2.1M to 3.0M] IIC profiles (1.1% of this group)." • "3.5M groomers (1.1%) [95% CIs: 2.9M to 4.1M], • 2.7M missing label (0.85%) [2.2M to 3.3M], • 18M potential groomers (5.6%) [16.6M to 19.5M], • 104M minor age liars (32.6%) [101M to 107M], • 192M non-groomers (59.9%) [189M to 195M]"
