[Redacted]: "As a result of major infra changes some time ago and reoccurring issues related to alignment of FB and IG deletion policy we haven't had FB→IG enforcement propagation [on u13 accounts] working consistently for over a year, and we've never had IG→FB enforcement propagation."

" If we know that a user is underage and they've also explicitly admitted to owning several accounts by hardlinking them via the account centre, we must enforce on all of them, not just the account that's been reviewed. ## Problem As a result of major infra changes some time ago and reoccurring issues related to alignment of FB and IG deletion policy we haven't had FB→IG enforcement propagation working consistently for over a year, and we've never had IG→FB enforcement propagation... We're inactivating around 30k extra Instagram accounts per week as a result of propagations from FB! That's 70% more than we were inactivating prior to propagation... This remains an important part of maturing our enforcement mechanisms and having defendable efforts - because these are accounts that we know to be owned by underage users."
