The problem
Hashes are burned forever
Meta and TikTok vision models and audio parsers do not wait for a human reviewer. They read the file’s metadata and binary hash first. If an ad is flagged once, that fingerprint is burned across every Business Manager you will ever open.
Re-uploading the “same” MP4 — even with a new filename — is still the same identity. Spend dies before the creative ever gets a fair test.
