What it is

Not an operator: the default user-agent of the most common Python crawling framework. Anyone can be behind it. Modern Scrapy obeys robots.txt by default, which is why the default UA is still worth a rule.

What blocking it costs you

You block a very large tail of unattributed one-off crawlers, and also every well-behaved researcher who did not change the default.
