They sent an email saying that of all the hacker issues they have with the websites they host (thousands I guess) the #1 security issue by far is people running outdated WordPress installations and hackers taking advantage of them. And they sent us a list of detected outdated installations and a threat that they would suspend our account if they aren't updated or deleted. I requested they run the check again tomorrow and send us the report but I don't know if they replied yet (to Roc).
