Joy noticed that my older version of WordPress was once again hacked to insert a list of drug names into the theme header.php file.
So, I upgraded. When I did, I noticed 24 comments that were made over a long course of time, all marked as Spam, but all not. Some of these were duplicates that I removed, and I approved the rest. I have no idea where these came from, because I could not see them before. Strange.
Took a look at the theme, which looks the same, but if anybody notices anything weird, please let me know by comments here, or by email at firstname.lastname@example.org
