Via fantastico, I used php form generator for one of my hostony email accounts.

I did this so that this account would not be spammed. I assumed that the purpose of a contact form is to protect an account from spammers.

Not so.

The form can be seen here: http://www.worldserviceworld.net/forms/form1.html

Just this morning I received 734 emails, all of them spams, one or two of them were actually sent via the form but most of them are direct emails.

This email account has NEVER been made public. It is NOT listed on my site. The only way to use it is through the form, or so I thought.

This must mean that PHP form generator has a hole in it or was specifically designed to gather and sell email accounts.
30 or so of the spams carried viruses that my Bullguard software nipped in the bud.

How did this happen? Just last week this account got no emails, now seemingly overnight I am deluged.

Please advise me as to what I can do about this.
