sorry, one more line code goes before that:

(int) $uid = $user->data['user_id'];

so the complete code looks like:

// Akismet SPAM check
if (($user->data['user_posts']<=6) && ($user->data['user_type']==0)) {

$akismet_comment = array(
‘comment_type’ => ‘comment’,
‘comment_author’ => $user->data['username'],
‘comment_author_email’ => $user->data['user_email'],
‘comment_author_url’ => $user->data['user_website'],
‘comment_content’ => $this->message,
);

$akismet = new akismet(‘YOURAKISMETAPIKEY’,'http://YOURDOMAIN.TLD’);

if(!$akismet->error) {
if($akismet->valid_key()) {
if($akismet->is_spam($akismet_comment)) {
$this->warn_msg[] = $user->lang['AKISMET_SPAM'];
$a_to = "EMAIL@WHERETOSENDNOTIFICATION.EMAIL";
$a_subject = "Attempted SPAM Post by ".$user->data['username'];
$a_body = $this->message;
$a_headers = "From: EMAIL@NOTIFICATIONSENDER.EMAIL";
mail($a_to, $a_subject, $a_body, $a_headers);

(int) $uid = $user->data['user_id'];

$sql = "INSERT INTO " . BANLIST_TABLE . " (ban_userid, ban_reason, ban_give_reason) VALUES (‘$uid’, ‘AutoBAN – posting SPAM’, ‘AutoBAN – posting SPAM’)";
$db->sql_query($sql);
$sql = "DELETE FROM " . SESSIONS_TABLE . " WHERE `session_user_id` = $uid";
$db->sql_query($sql);

}
}
}
}

Hi Mark,
after i’ve got tired of banning all those spammers on my board, i’ve extended the script a little bit, so it also bans on spam attempt.
Maybe it’s not very polished as it is now, but it works for me.

After mail call, in your script, i just added:
$sql = "INSERT INTO " . BANLIST_TABLE . " (ban_userid, ban_reason, ban_give_reason) VALUES (‘$uid’, ‘AutoBAN – posting SPAM’, ‘AutoBAN – posting SPAM’)";
$db->sql_query($sql);
$sql = "DELETE FROM " . SESSIONS_TABLE . " WHERE `session_user_id` = $uid";
$db->sql_query($sql);

which adds that user to banlist table and deletes his session, so he gets immediately logged of.

Hi Mark,
many many thanxs!!!
your solution works perfectly and akismet can catch about 98% of spam posts.
Really wonderful…

One idea, though.. it would be great, if you can also implement warnings and banning. Let’s say, after 1st spam post, warning will go to the user. After another spam post, user will get banned

one more time THANK YOU!
I highly recommend this to every one, using phpbb3. No more WOW gold and stuff like that.

Yeah, I set up daroPL_AntiSpam to help prevent automated signups and my Akismet solution for people manually trying to spam

Hi Mark,
many thanxs.. this looks very promising.
Last days i am also dealing with shit loads of spam at my forums and it all seems to be manually entered spam.

i’ll try your solution and will let you know, how it goes…

One question please… How about the “phpBB3 mod called daroPL_AntiSpam”?
Do you actually use it along with your Akismet solution?

thanx

Please remember to replace the obvious with your real information,

e.g.
YOURAKISMETAPIKEYHERE = The API Key you have gotten from signing up to WordPress.com
http://www.yourforums.com/forums = URL of your forums

..and the email from & to names/addresses

Also please note that I made these mods to phpBB 3.0.5, so you may not be able to find some of the code if you’re using earlier versions, though I think it’ll probably be there in all previous 3.0.x versions
