You're right that plenty of operators just delete and move on, and that's a real gap. Two things can both be true: reporting to NCMEC is mandatory under 18 U.S.C. 2258A for US providers, and a lot of them still don't do it well or at all. The law sets the floor; actually running PhotoDNA and the Cloudflare and third party scanning, plus the staff hours to triage hits, is well above it. One honest caveat on PhotoDNA specifically: it matches hashes of known material, so it catches what's already in the database and misses new stuff. It's a strong net, not a complete one. Same with the classifier models, they trade false positives for recall. So "we find ALL CSAM" is stronger than any hashing or model pipeline can actually guarantee, and I'd phrase it as "we scan aggressively and report everything we find," which is both true and more defensible. The cost point lands too. Scanning, storage, and human review are exactly the parts that eat margin on a service that's barely breaking even, and they're invisible to users who just want a fast upload link.
