New wave of AI generated spam

I'm seeing a new wave of apparently AI-generated spam sent to the service addresses of my domains -- root@, postmaster@, and webmaster@. Anyone else seeing this? Subject lines are usually "Quest" or "Question" or "Lite" or "Lost" -- here's an example (nearly the same body text in each message):

Wow, that's next level. I haven't been the target of that yet /crossfingers

How is it travelling to you? Are they using VPS's, email sending services or Gmail/Outlook? VPS's can be fenced but the later is difficult to block without affecting legitimate traffic.

Two different IPs in German data centers are sending it -- from a .bet domain and another .ru domain. Some are posing as being from @samsclub.com. I have the IPs blacklisted and for now I am disabling webmaster@ service e-mail. (I won't break RFCs by disabling postmaster@ e-mails.)
