Adding on to the SQL database errors noted by others above, ones in which the punch line is "MySQL Error : MySQL server has gone away," I do believe that most of these have to do with the MU hack. But, isn't this what the MU modification is supposed to do? Delay response?
I have this one particular spammer I MU'ed who is particularly determined to get back on my forums. Or maybe he doesn't even realize he has been MU'ed and just thinks this is the way it is!
Anyway, the errors typically read like this:
Database error in vBulletin 3.8.4:
Invalid SQL:
SELECT forumid, moderatorid, permissions, permissions2
FROM moderator
WHERE userid = 313 AND forumid != -1;
MySQL Error : MySQL server has gone away

(By the way...just FYI, through these database errors I have noticed that the culprit logs on with different (but very similar) IP addresses. So, banning an IP address is not an effective means to keep away a determined spammer.)
But the odd thing is...I am also occasionally getting these database errors for unregistered users:
Invalid SQL:
INSERT INTO cronlog

1251271198,
'Google Sitemap Created',

And wonder if these cron errors also have to do with this MU add on.
