I’ve completely migrated to Debian last year, and one of the issues was ICQ antispam again. Official Debian repository lacks Bot Sentry plugin for Pidgin, so I had to build “quick-n-dirty” package myself. Binary .deb for i386 platform (Debian Sid) can be downloaded here and installed with
$ sudo dpkg -i <pkg>
$ sudo apt-get -f install
For other platforms you can download source package and rebuild it.
I am not going to adopt the package into official Debian repository, since Bot Sentry upstream seems to be dead and there is a good replacement already there. I would recommend it for novice users. But for those accustomed to Bot Sentry here is the chance.
BTW, Fedora package is also updated.
