Funnily enough, I haven't been running vBulletin for nearly a year (sign that Google doesn't understand my site?). Not only that, but the link to the blog post about the subject indicates that the feature has existed since 2009. So I never got the notice for the years I was running vBulletin, but 9 months after I no longer am, I get the message??

whoa, that's messed up ... stuff. Sounds like a spider regurgitation.
