My guess is it depends on the damage this attack will cause. If the missiles are all shot down or hit desert, it will be some punitive F-35 strike on an Iranian airfield somewhere. But if there’s significant damage and casualties it could escalate.
I don’t think Iran is going to risk all out war with Israel and the US. I suspect they expect most of their missiles (like the drones) to be shot down. Perhaps that’s wishful thinking though…
Companies use the same kind of systems to (poorly) automate the search for candidates, which is also spammy, inefficient, and wastes job-seekers time. This just levels the playing field.
