Comment spammers
I have been spared the invasion of the comment spammers because my weblog was offline this summer.
But to pre-empt them, now that comments are back, I installed Blacklist. I then did a Google query on blacklist.txt, and pasted the first few results in my blacklist, thereby updating my list before the spammers even hit me.
Here's my list, compiled out of various sources (I don't think sharing these would help the spammers, would it?) It certainly feels goood. I'd be up for an option in blacklist that automatically gets other people's lists.
