in reply to How to use tr///

Sorry I should have offered a better explaination. 
$value =~ tr/[/url][/[/url] [/g;

The reason I am trying to use the code above is: I have someone abusing one of my web forms. They add lines in the form which include [/url][. So, I was trying to write a bit in my script that picks this up and recognises it as this abuser and stops him from being able to send his spam through my form. I have tried IP blocking but he obviously has a dialup account and it keeps changing his IP address, so the next best thing I could think of was to block him when the script sees this text. If anyone has a better idea on how to stop people from abusing my web forms it would be appreciated. Thank you again.

    Did you write this code or did you get it from somewhere on the net? Can you post the code here? The reason I ask is that there are probably other ways to exploit your form and this fix would just be a stopgap.

        That code is full of bugs and security holes. I suggest you try one of the NMS CGI Programs instead; they're not vulnerable to those flaws.
