Apologies to anyone who saw a post with an explicit video posted on ATR. (Or ended up with it in their RSS feed.) It seems the blog was hacked somehow. I’m going to contact WP and see what steps I should take to address it.
UPDATE: In the meantime, I’m going to change the blog’s settings to hide it from public view until I can sort out what to do.
UPDATE 2:And…we’re back. It looks like the problem originated in my e-mail account. Someone hacked into it and sent a message containing the video to all my contacts. And because I have the “post by e-mail” feature enabled on my WP account, it appeared here too. I’ve taken some steps that hopefully will prevent a recurrence.
