I had about 20,000 porn spam postings when I was initially set up. I had to lock down all the forum categories to block the spam.
By “lock down”, I mean, to configure it so that only the SysAdmin had posting privileges.
For the case of this first website, that was OK because I’m using the forum as a handy place to post renderings and other computer graphics stuff, so it’s OK to block people from posting (i currently have about 30,000 porn spammers registered on my website).
However, I would like to learn how to set up a forum where normal people can have posting privileges. I assume the “Captcha” thing where you type in the words or letters in a graphic, that’s one way that you keep out the robo-porn-spammers.
My guess is, I’m not the only person who’s been presented with this situation. Is there a tutorial or a FAQ or a How-to or a Wiki that illustrates the HTML for the page(s) you would need ?
I guess the “Captcha” is usually used by websites at registration time.
