PHP-General - Anti-spam: can I retrieve location from where is posted?
Background:
I've got a guestbook which some bots like to use as an advertisement location for their x-rated sites, and basicly, I don't want them on my site.

My question is as simple as this:
is it possible to retrieve the location where a $_POST is coming from?

When writing something into my guestbook, I want to know if a user uses my own written 'guestbookwrite.php' or uses another self-written form.

do a print_r on the $_SERVER variable, it shows the page they're coming from, the browser they're using, and their IP address.

All of which will be spoofed to look like a valid request by any decent spammer. Basically, the only way to really prevent the spam is screening it, be it via a captcha, or manually, or some other method.

That is an article detailing the method I use on my site to prevent guestbook/comment spam. It has worked almost flawlessly for me since implementing it. It wont stop anyone intentionally targeting my site, but it does stop most all the auto-post programs out there. Feel free to look it over and use it if you wish.
