Alex_K's script which wilderness directed to is a superb start and is the foundation of my bot blocking, although i've morphed into my own variant over the years.

what i would say is that it is very time intensive trying to block bots, however you can do a lot, save a lot of bandwidth and processing power on your server with just the basics.

you can block an awful lot by making use of the two threads pinned to the top of this forum, getting an ip to country database (paid or free) and blocking countries that it makes sense for you to block (could be different to other people)
