One way to combat comment spam is to display a random alphanumeric
string near the Submit button and require your users to enter that
random string in order to be validated. The string can be generated by
Javascript so that a web spider reading HTML pages won't see what a user
with a browser is seeing. Perhaps even better, place the string in an
image - this eliminates spiders crawling through an automated browser
interface and eliminates the need for your users to have Javascript
enabled.
