Previous discussion, just long enough ago that I’d forgotten the name:

User-Agent: undici
IP: The Usual Suspects
robots.txt: no
IPs include a scattering of 63.176.blahblah, which I hadn't previously known was AWS. It's a pretty hefty range, some or all of it based in Germany:
63.176-191
63.176.0.0/12
(Cross-check of logs turns up nobody else from this neighborhood. Yet.)
Blocked on grounds of bad_range (most of them), bad_agent (pattern ^[a-z ]+$), and one other header deficit.
