We are getting lot of spam tickets. I have exchanged emails with your support team and the resolution you provided is not enough which is flagging the ticket as spam, blocking the sender etc.
First of all you need to stop the spam bots by making support ticket form spam protected.
Easiest way is to have the honeypot hidden field and robust way is to have reCAPTCHA code.
Following is an example how Pardot implements the form handlers to make them spam protected.
Please implement similar techniques in your form too.
