No discussion of account restrictions, including topics that try to discuss something else so that you may bring up your account’s restriction. Your account is under restriction because you distributed content that very obviously portrayed children in a sexualized way. “old collab partner sneaking something sus in a very old project of mine” is no excuse, you take full responsibility for everything you upload.
Account restrictions exist to protect our platform from bad actors. Although it’s unfortunate that legitimate users may be affected, we do not share the specifics of our review policies at this time to prevent manipulation of the systems. Individual account issues must be handled directly through support.
