I'm a bit surprised that's still around. Over a year ago it hit multiple IPs in our Class C so I nuked its server farm's access (208.94.243.13*). Another time the UA hailed from another server farm, hostnoc.net. Anyway, after enough of those kinds of hits, I decided earlier this year that the likelihood of a real someone still running a Nov., 2004, Firefox was slim and opted to redirect all of them (to an info+e-mail page).
("x.x.x" is a nifty tell for blocking. Ditto "2004" for me.)
FWIW, I tend not to report obvious fake UAs, alterations, or Yet Another Nutch variant because they are limitless and 99.99% misbehaved -- unless a fake UA is involved in spidering/crawling from one or more addresses. Like the asinine mashup:
Googlebot/Nutch-1.0 (Prototype; http://en.wikipedia.org/wiki/Web_crawler; donotreply at prototype dot com)
That's block-worthy on so many levels:)
