How is any kind of antivirus or threat detection software supposed to operate on this standard?
Libel suits can be financially catastrophic, so even a tiny false positive rate could present risk that disincentivizes producing such software at all.
And a threat detection mechanism that has a 0.0% false positive rate is conservative to the point of being nearly useless.
You document your claims with concrete evidence of fraud. That will be your libel defense. No evidence means you bear the full responsibility of a fuckup.
I think that is the idea. They shouldn't exist without a prompt mitigation path.
In other words, if you can't deal with the false positives in a timely manner. You SHOULD be liable for the damages.
I can't build a budget car put together in an unsafe manner. Then complain I can't compete due to all the peoples cars crashing and blowing up and suing me.
