bbAntiSpam: Discuss how to stop web spam

[Brewer]

I installed the Textual Confirmation in my board
http://www.excelential.com/bb

1. Download Advanced Textual Confirmation from
http://bbantispam.com/atc/AdvancedTextualConfirmation.zip

2. Unpack the archive to get the files
"bbantispam.php" and "bbas_config.php"

3. Change the questions in the file "bbas_config.php"
I used:
$questions = array(
'Are you a spammer?' => array ('no', 'nein', 'nope'),
'What product is this forum about? (hint: look at the domain name)' => array ('excelential', 'xcelential', 'excelential.com', 'xcelential.com', 'excel', 'dashboard', 'dashboards', 'excel dashboards')
);

4. copy bbantispam.php to bbantispam.php
copy bbas_config.php to bbas_config.php

5. then modified common.php to start with

<?php
include_once($phpbb_root_path . 'bbantispam.' . $phpEx);

6. then I disabled visual confirmation.

THEN I tried to register in the board ( www.excelential.com/bb )

after uploading the files, it worked! I got the textual confirmation, which refused to let me past until I typed a correct

Unfortunately, when I tried to submit my registration, I got:
"The submitted form was invalid. Try submitting again."

When I undid my change in common.php, the problem went away.
I applied the change in common.php and the problem is back.
( and I let is stay, so now users can not register in the forum. you can try it yourself )

Can you help me fix this?

Strange. I've tried to register an user (the name is "test"), and everything went without problems.

Probably it's not an error due to the Advanced Textual Confirmation, but a feature of phpBB3? A quick look at Google suggests, for example, a possible explanation:
