Fighting NON-regular expression spam
How about having a look at Manual:$wgSpamRegex?
That's what he is using, Hazard-SJ.
What about adding "==<center>[http://" to your $wgSpamRegex? (I'll add this to $wgSpamRegex's documentation too; it's quite common.)
I read it, and I did add it to my line, but it doesn't seem to work. I assume that it wasn't picking up actual HTML commands, only regular text. Otherwise, I don't know why it would not work. I'll try it again. Let me be a little clearer.
Here is an example of one of the edits a typical spammer makes:
==<center>[http://mylinkdirs.com/forum/index.php?topic=mp7MjE3fHwxMzAxNjA0MTY1fHwxOTUyfHwoRU5HSU5FKSBNZWRpYVdpa2k%3D&s=Atkins_Diet_Side_Effects_Bumps <big>'''<u>Atkins Diet Side Effects Bumps</u>'''</big>]</center>==
I created the following line in my LocalSettings:
$wgSpamRegex = "==
But it doesn't help. Should I be adding something else?
Not only is it not working, but it seems to have "broken" my
require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" );
tag which I was using to confirm anyone who posted links.
