Is this another of those arrangements (weren't we just talking about this a few days ago?) where they're visiting your site in response to some other human's lawful action, and should therefore be tolerated? Or are they up to no good?

Probably "no good." Jetty (more info at source posted above) is a utility that can be used for many purposes, including GET to mine data from domains and form libraries, indexes, etc. In other words, it can be (and is) used as a scraper.

However, Jetty is also being used to gather data to populate Social Media platforms. I recently have seen it used to build a short link resolver DB. In that instance, it would, IMO, be "tolerable" but for defense simplicity, I'm currently just blocking this UA. ymmv.
