Won't the scammers not just use this to improve their campaigns?
A scam might, for instance, say "If you don't go to phishingpage.xyz RIGHT NOW your account will be DELETED!" to capitalize on urgency. That appeal to urgency can be detected. The scammers could of course just choose not to appeal to urgency, but then that would reduce the number of people who'd fall for their scam.
Another domain, but the same result [1]. Better detectors just yield better fake.
