Good post !
I can suggest two other trends to watch out for:
Hyper-personalisation. Scammers have access to so much data, and so many tools that can pull information from your social media or even your own device, that it's becoming ever-easier to make every scam ad directly addressed to the recipient - "Hey Fred Smith, your ABC bank account number 12345678 has been viewed by the IRS X times this week. Move your $1234.56 to DEF Bank now to be safe from investigation !"
AI-driven anonymisation. In my business I'm seeing it already. Most of the messages on my website contact form are spam. But captchas no longer work because AI's can solve most of them, and banning sender IP addresses no longer works because the scammers are generating a different IP address for every single message.
It's also a problem with any software which prices based on views, searches or clicks. I had a huge dispute with DooFinder because in the last 6 months competitors have started to routinely use AI-generated searches with dynamic IP addresses to price scrape. But DooFinder charges using price bands based on the number of searches, so they were happy to make money off it and refuse to listen to an easy solution that would identify the fake hits.
