Great Job ! ^^

Actually, though certainly not in the same proportions as you do, I also have a lot of spam to fight. I finally decided to abandon Akismet, which was not as powerful blocking spams as Antispam Bee. Maybe it's due to the fact that I blog in French, I don't know.

Nevertheless, AntispamBee is efficient enough for me to leave comments open have a very few spams that break through, while have a "do follow seo blog with Keyword Luv" which is a honey beacon for spammers.

I also had to desactivate the pingbacks / trackbacks and feel sorry about that : it's kind of unfair for the people doing genuine links, also it prevents my readers from getting informed about potentially interesting posts.
