Hello,

I.ve looked every where for a script or a tutorial that would tell me how to stop guest books and forms being used by bots. I have a guest book that I used for the first time and it's filing up with spam.

1) Is it possible to limit the number of posts by people. I think this may stop bots too? I was thinking of maybe using cookies, but what about bots? Do they accept cookies and such? What if the post has cookies disabled?

2) How do I get my form to stop posts. For example, only allowing one post every thirty seconds?

3) I've seen other forms have randomly created text in an image. I don't know how to do that, but I though that maybe I could make 10 random text images and then display one randomly.

Any help would be appreciated.

Why bots are filling in there?
If it is, isn't it good to you :D

1)
See, activate an entry after poster click some link, send to him/her in his/her e-mail. I mean, force poster to confirm his/her e-mail.

2)
Use PHP gd library to write something randomly on a background image, and force posters to confirm the code, they see on image.
