To install, copy autoblock.c and autoblock.h to /path/to/gaim/sources/plugins and type "PLUGIN_LIBS=-lpcre make autoblock.so". Then copy autoblock.so to your gaim plugins directory (On unices it is ~/.gaim/plugins). The files ab_nicks.txt and ab_messages.txt are supplied; I spent a little time culling them; and they get most of the bots in the rooms I have been in. Copy them to your gaim home dir (~/.gaim on unices).
