spam guard

[garikr]

I'm still flip-floping about what am I gona do with my site, but one thing's for certain, the will be a comment area. Almost every site, which allows you to leave comments, requires you to login, that alone stops me from posting 70% of the time.
I'm thinking of letting visitors post without logging in. But how do i stop that one immature cyberterrorist wanabe from flooding/spamming. I was thinking about limiting the number of posts allowed per day per user( maybe tying it to the overall number of visitors/posts somehow), or do the human test/question, or both.
Any thoughts, suggestions??

Thanx for the post, that's a lot of code though... , I already have a bear boned messaging system, gona look through your code to figure what I can use. I wish there'd be a little more comments... Probly a good idea to start putting comments in my code.
Thx again.
