Odd UA acting bad

[tangor]

UA: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko
MS Azure
23.101.171.xx
52.240.137.xxx

Aggressive, two days (I was away), ripped entire site multiple times. UA seems "incomplete", at least in my experience.

Cloud rather than genuine user? Most requests originating from cloud services are problematic at best these days.

:: detour to raw logs ::

I find a fair number of this UA, every last one blocked :)

:: further detour to logged headers ::

Aha. They don't send Accept-Language. That would do it. (Also only the minimalist Accept: */*, used by a number of law-abiding robots but no humans.)
