Very handy – I tarpitted a silly one yesterday after their first attempt and watched another 9 failed submissions timeout, but today’s one was coming from a botnet (no fixed IP) and going directly to the posting file for articles that didn’t exist. As it was starting from post number 1 I got tired by the time the fifth item came in, and so used the very simple block shown at the head of the above page to stop them.
Now we’ll see how clever they really are: if I get new submissions with a correctly spoofed referrer then they’re reading my blog too ! What fame !
