Meta is "launching more new products at a faster rate than ever, each of which require additional work to prevent abuse" but "We aren't staffed to both integrate with FB and do IG specific work to stay ahead of all potential PAC [Protect and Care] related issues."

"However, there are five areas you should be aware of and I could use your help addressing:" "5 Instagram PAC is far behind FB PAC and we could become a major liability for FB Inc." "Instagram is now over 850M monthly users, and with that size comes the responsibility to ensure our community is safe. Also, we're launching more new products at a faster rate than ever, each of which require additional work to prevent abuse and reduce exposure for FB inc. We're continuing to see an increase in high intensity abuse and an increase in regulatory requirements, including GDPR." "However, the PAC team is only 22 engineers. We aren't staffed to both integrate with FB and do IG specific work to stay ahead of all potential PAC related issues. To solve this, we are working with FB Integrity leads to (1) staff more IG-specific PAC engineers to focus on measurement/labeling, top account security, and tooling and (2) to staff IG-dedicated engineers on the FB/PAC team to support the x-FB Integrity Framework. In 2018, we will staff up this team significantly, though we are starting from far behind."
