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. _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
