Ipstenu, thanks for your help.

Looks like the nonce field is very important to prevent spam posting.

Form submitting doens’t work if you specify a wrong nonce. Take a look at my searchings:

post_form’s _wponce, what is it?

http://phpdoc.ftwr.co.uk/bbpress/bbPress/_bb-includes—functions.bb-pluggable.php.html

http://svn.automattic.com/bbpress/trunk/bb-includes/functions.bb-pluggable.php

You can create a nonce key with this funcion:

bb_create_nonce();

I will continue with the searching and testings.
