I started a wp blog in December of this past year and get hammered with spammers – I have the comments set to admin approval so none of them ever get posted, but its a daily task going in and trashing them all just the same. Its amazing what some idiots out there will try to get posted on someone elses sites.
Be nice to be able to treat these comment spammers the same as email spammers and have their ISPs take action against them.
