You can save data within the database where you can check if the form have
been submitted and
it will not be resubmitted
A table with a name like "banlist" will be always good for alot of uses and
not only the check for submitted forms
for security image code checks, ip/hosts bans, bans on bad words or bad
actions (if someone tries sql injections, XSS, file inclusions etc).
Another solution could be to not resubmit a form if a cookie is set. A
problem could arise when the browser doesn't support cookies or they are
disabled.
I hope that those things could help you.
