I know that the math captcha has been cracked. I use the same extension 
on my highly trafficked wiki.

I switched to the image captcha and that has stopped 99% of the spam 
link edits. However, there are still spam bots editing my wiki that I 
cannot stop. Instead of spamming links they just delete a majority of 
the page text. To block this I protect all effected pages for about 2 
weeks and it stops it.

I've given up on the IP blocking. They use every open proxy on the earth 
to randomly attack you.
