I see hundreds of /trackback/ and wp-comments-post.php POST requests
ever hour for the WordPress sites I host (have about ~210 or so) and
mod_security really helps immensely, and for the SPAM that does go
through, there's always Bad Behavior, Akismet and Spam Karma. like you
said, it's like a DDOS attack, none-stop across several hundred sites,
but that's reality. and being that someone responsible for those sites
mean, i have to ensure they're protected appropriately.
