Captchas don't protect against captcha-solving services which run at around $4 
per 1k captchas. If someone decides that spamming our wiki is worth more than  
$0.004, then captcha can't help. Such services however only parse pictures so 
if there are any nonstandard steps required to post, 99% of spam would 
disappear.
