I apologize if you got a whole bunch of messages.
I woke to dozens of Sucuri Sercurity alerts about new posts but there didn’t seem to be any. I signed in to my dashboard and boom, a bunch of things published (although don’t actually appear to be on the site)–new post emails and twitter alerts went out. I’m combing through the Sucuri logs.
I’ve updated things and changed passwords, and disconnected the site from Twitter. Again, I’m sorry for any confusion.
If this weirdness sounds familiar and you know wtf happened, let me know, because I’m fairly clueless about this stuff.
