Instagram head Adam Mosseri on Friday addressed the moderation issues that saw Instagram and Threads users losing access to their accounts, having posts disappear, and more, saying that the company “found mistakes” that it’s attributing to human moderators. The company did not initially blame faulty AI systems, as many believed would be the case.

In a post on Threads, Mosseri addressed the issue that has been plaguing the social platforms over the past several days, adding that the mistakes it’s found so far were due to content reviewers — people, not automated systems — “making calls without being provided the context on how conversations played out, which was a miss.”

His explanation doesn’t seem to fully account for the range of issues that users were experiencing, as some found their accounts erroneously labeled as belonging to a user under the age of 13, then disabled. It’s unclear how a human moderator would have made this assumption. In addition, according to a report by The Verge, even after a user submitted their ID to verify their age, their account still remained disabled.
