As a reminder, last year EY conducted an independent assessment of the metrics in our CSER, as the first report of this kind with third-party validation. I believe it's an important part of keeping ourselves in check. about.fb.com/news/2022/05/c (4/7)

Community Standards: our goal is to keep prevalence of violating content down while minimizing mistakes on the content we remove. There will always be examples of things we miss and things we take down by mistake. This report is the best way to evaluate progress. (2/7)

The spoof was set up as a free trial Workplace account under the name “Instagram” and using the IG brand as its profile pic. We've locked the account for violating policies and are continuing to investigate. We'll provide further updates as warranted here:

In its October 10 story, links to a supposed internal report about the incident in question. It appears to be a fabrication. The URL on that "report" is one that’s not in use. The naming convention is one we don't use. There is no such report. (3/6)

The stories are simply incorrect about the cross-check program, which was built to prevent potential over-enforcement mistakes. It has nothing to do with the ability to report posts, as alleged in the article. (2/6)

Meta has named Guy Rosen as its first (!) chief information security officer, elevating his portfolio to the C-suite of top executives alongside that of the chief privacy officer, employees told me. 1/6

We welcome their conclusion that we’ve presented these metrics accurately and we have the right internal controls in place to ensure accuracy. As we keep growing this report, we'll also keep working to make sure that it is independently verified. about.fb.com/news/2022/05/c (7/7)

For the second part – are our answers correct – two years ago we committed to verifying our metrics. We engaged EY for this assessment, providing them in-depth details about processes, systems, controls, and gave data and evidence requested. (6/7)
