RE: FN-FORUM: form spam block

In that case, and if you're using PHP, try something like;

//prevent email strings
if((strpos($name, [EMAIL REMOVED] || strlen($email)>50 || strlen($name)>30 )
die();

At least they'll have to do every individual email by hand rather than
loading the email field with addresses.

Craig,

I just had a look at your contact form and although your challenge-response
looks like the example, your site actually drops a plain (i.e. screen
readable) piece of text over a coloured background, instead of generating a
complete image with the text embedded (i.e. not screen readable).

Your form is still easily crackable by a slightly modified script engine
(unfortunately).

It wouldn't surprise me if there are people who get paid to send spam mails
via forms though!
