Wish you'd warned us, IncrediBill! :)
I test bot UAs against declared or otherwise known IPs, sometimes shortened UAs, sometimes (as in scoutjet/blekko) the full UA. This helps in prohibiting bad UAs from good bot IPs, which I'm seeing a lot more of lately.
I usually pick up changes fairly quickly but this UA change slipped by me for at least a couple of weeks.
