Hackers have been at my wordpress database and filled it with links, mostly hidden with a display:none style, to all kinds of spammy things. Very irritating as I’ll have to spend some time cleaning up. Unfortunately my sql-fu and my regex-fu are not really very powerful so this may take a while. Time I should be spending on something else!
Looks like I’m going to have to edit the posts table offline, so first thing is to use the delete revisions plugin to remove the unnecessary items in that table.
