The second option is:

It also claims to hide your web sites from the spammer’s eyes so you won’t even be bothered by those inconvenient friends! And they promise more benefits, such as a shorter web site loading time, clean site logs, and prevention of other problems caused by spam.
The third option is:

NoSpamNx claims not to use any javascript code, cookies, sessions or captcha system, which is an excellent option to keep your WordPress code clean.
