For reasons too bloody tedious to go into, I'm getting a lot of unwanted e-mails. I've worked out how to block mail from certain addresses (tee hee even if I was suicidal I'd live just to spite you fuckers). I mean e-mailing 'Kill Yourself' to someone a million times a day takes up space in ones inbox and is about as likely to lead to suicide as sunshine.
Anyway I'm looking for some technical help. Is it possible to block certain IP addresses from commenting on one's blog? I'd prefer not to resort to the dreaded comment moderation if at all possible.
