Thanks for the thoughts but the actual range I'm blocking is only 8192 IPs (122.99.64/19). Those I would deem "dodgy" are actually about 512 IPs - the top /23.
But a compromise: I'm now blocking 94/23 and allowing the rest of the /19. :)
Have to say I'm also a bit more careless about certain ranges such as RU, UA, CN, KR, VN, BR than others when it comes to blocking. I do a rough check: if it looks server-ish it's blocked, otherwise it's put on probation (I have a category called "badcountry" which a small proportion of my UK-centric sites reject). I sometimes think wistfully of adding US to the list... :)
Mind you, I'd also like to block UK ones at times, and I live here! :(
