Most, if I can, in this neck of the woods of WebMasterWorld shoot(block invalid requests) first, then investigate later, me included...
We come to "Search Engine Spider and User Agent Identification" on daily bases, sometimes more often for access control freaks, like me again.
One thing I have to state that it works. Been here since I got one of my domain addresses 'SNIPPED' describing(spilling my issue), and later was flying under the cloak of "Scraper Slayer"... Man, It is almost addictive...
I surely wont blanket block anything but certain countries.
In my book, lately, I'd go against SF(server farm and such) list first coupled with request headers(except CN, UA, KR, BR, NL ...) before I'd block the user.
