It looks like this site was hacked.
I was looking as some of my stats and noticed some weird keyword that I would not use (Canadian geese, Trump).
I traced the posts back to an
IP, and followed that
IP through some logs.
In the logs found the hole they used to get in. It was an
out of date plugin, like always.
I have gone through and removed all the bad posts and have patched the holes, so the site should be good to go.
