Preventing Spam

Question

How do you stop bots on a page which is accessible to registered users only? 90% page is accessed by real users and 10% are bot.

I do not want to put captcha or veri

Answer 1

One trick I like to use is to add a hidden input field to my forms that a real user would never see or change, but that a bot would blindly fill out.

Something like

and then, in your form handling code, make sure the value of spam_stopper is "DO NOT CHANGE THIS".

A smart bot may ignore display:none, but that's not too likely - many do ignore though, so I wouldn't use that...
