Preventing new ticket creation based on certain words in subject and content

Hi All,
I need to prevent creating a new ticket when a specific word is found in the subject and in the content.

Is this possible whith custom scrips ?

Thanks in advance for you help

By the time a scrip is running, the ticket object has already been created (which is why the scrip can access it). I guess you could have a scrip that moves a matching ticket to a status such as rejected immediately on create, and then let your nightly shredder run get rid of them.

You could also write a mail plugin:
