I skipped from 3.3.3 to 4.1.2, but I was also troubled by the lack of report to central happening in the output.

After some looking around in the code...the solution is here:

--- antispam.ctrl.php.orig	2012-01-22 12:00:01.000000000 -0800
+++ antispam.ctrl.php	2012-01-22 11:54:59.000000000 -0800

 		{

If you read the comment in the blacklist_locally section...it says

// We have EXITed already at this point!!

So, the reporting after local blacklist doesn't happen.

I suppose the alternative is, if you want to report...don't do local blacklisting?
