I finally gave up and stop de-spamming my blog. Well, that is not a problem since the release of MT 3.11, optionally MT-Blacklist do not allow comments to come up unless I approve them. This saves me lotta embarrassment and mails from my host blaming me of having illicit links on my blog. Recently, with the update to MT 3.12, 3.121 the bug with comment count have also been solved (previously, it was counting the number of comments that have not been approved, I found it long back in the 3.11 beta but fixed in 3.12 release version).
Now, the issue is no longer the spam, but authentic comments. I have to wade though all the spam to find which one is the authentic comments for me to approve. The internet world is never going to be an easy way to surf along. But come-on, I am ready to face you scums.
On the e-mail front, Spamihilator is proving to be a real cool free tool for me. It stops spams before hitting my inbox. After a bit of training, it is proving to be really effective in wading away spam mails. By the way, SpapFiles have some cool free tools.
