Best way to protect against spam?

I haven't done anything yet on my site http://www.tinemuller.dk/drupal/ to protect against spam - is a testsite but soon I will make the real site and need to know what best to use. Is http://drupal.org/project/mollom the best to use or what do YOU use? I have heard that several people have problems with Mollom.
Depends
It depends on what you are trying to do.
From my experience, Mollom works pretty well to protect textareas where humans (or bots) might enter enough text that a Bayesian spam filter would have a chance to make a determination about spamminess. It works pretty well on comments. Mollom refrains from putting up a CAPTCHA unless it's unsure, so it avoids annoying legitimate users.
If you need to protect an input form from bots and the form lacks juicy text for Mollom to analyze, skip Mollom and go straight to a combination of CAPTCHA and ReCAPTCHA. (The standard graphical CAPTCHA sucks, and ReCAPTCHA fixes that.)
There are some problems with Mollom if you're running a very complex site through a reverse proxy, but those are unusual cases.
