[development] My site is under attack (trackbacks, spam and cpu usage).

Yes, this has happened to me. I redirect their traffic back to them:

RedirectMatch /comment/reply/.*/comment/reply   http://127.0.0.1/
RedirectMatch /node/.*/trackback.*              http://127.0.0.1/
Redirect /cgi-bin/mt/mt-comments.cgi            http://127.0.0.1/
Redirect /trackback                             http://127.0.0.1/

Alternatively, you could block all the IPs at the firewall (thus, 
dropping the traffic instead of responding to it, above), but that's a 
bit more difficult to do unless you own the box.
