Finding 'http' or 'www'

[john noble]

I use a guestbook script which sadly get s abused by spammers.

99.9% of the span contains the text 'http' or 'www'. Is there a way I can search for both of those strings and if I find them - exit the script.

I have no experience with PERL so I need help with this one.

Thanks,

That SEEMS like a pretty simple problem

if ($message =~ /(http|www)/) { exit; } # regular expression

BUT
I have no experience with Perl (not capitalized)
Do you know where to put that?
Do you know how the $message variable gets set?
Do you REALLY want to exit; I think not!
What about valid posts to your guestbook that contain those strings?
