Almost nothing is actually wrong with the engineers building anti abuse systems. The infrastructure itself is reactive by design, and that design is the root cause. This is the diagnosis, and the one rule that would change where every system begins.
Every system built to protect people from online abuse waits for the moment that matters least. It waits for publication, when the harm already happened at the threat. This is why that gap exists, and the one rule that closes it.
Most anti-abuse systems start at publication. Panah starts at the threat. The most important decision in the whole project was a refusal, not a feature.
