Requiring Javascript to post data blocks a fair amount of spam bots while not interfering with most users.
You can also use an nifty trick:
<input type="text" id="not_human" name="name" />
<input type="text" name="actual_name" />
<style>
#not_human { display: none }
</style>
Most bots will populate the first field, so you can block them.
Ergänzung: Mit Javascript eine Zahl eintragen, die auf unserem Server geprüft wird.
