I offer some metaphors bundled into a claim:

Silver bullets almost never beat fraud. Better to steel yourself for a never-ending grind against a horde of nameless adversaries.

I asked Gemini for some follow-ups, and lo! they are interesting to consider:

- "fraud is an evolutionary arms race fought in the trenches."

- "fraud is a siege where the attacker has infinite attempts, and the defender must succeed every time."

- "fighting fraud is not a battle, it is industrial waste management."
