"msnbot-media" is old news. But this one-hit wonder came by today:
\"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534+ (KHTML, like Gecko) MsnBot-Media /1.0b\"


That's entire line's verbatim, including the escaped quotes. Oh, and:

robots.txt? NO
referrer? YES (also atypical)

The "b" in "1.0b" suggests beta, so that may give credence to your impression it's "sloppy." Or it may just be the successive release after 1.0a. However, as you say this bot is not new, and I'm pretty sure I've been seeing some version of it for a decade. What I'm seeing at my sites is:

65.55.213.244 - - [08/Aug/2015:00:42:31 -0700] "GET /robots.txt HTTP/1.1" 200 1229 "-" "msnbot/2.0b(+http://search.msn.com/msnbot.htm)

No escaped quote

Well, don't keep us in suspense ;) Who did they claim sent them?

Page only, or full package?

Got a vague idea I once tried to block the \" configuration but couldn't figure out how to express it. You never know how many backslashes is too many.

keyplyr: I get the beta indicia, of course. But all-lowercase msnbot-media's at least up to 1.1, even though it's been around for years and years; and this was not the also long-seen "msnbot/2.0b" variation. Plus I've never, ever seen included-and-escaped quotes with any MS bot. Those are Coding 101 bloopers.

lucy: The referrer -- atypical to see one at all with msnbot -- was a legit link, albeit a very old and rarely seen one. The one hit (which was 403'd) was to favicon.ico, not precisely the "images and video" claimed by MSN. [bing.com...]
