There are several different ways that readers can start following your blog. Note that followers do not need to be registered with WordPress.com. Anyone following your blog with an email address that’s not associated with a WordPress.com account will be sent details of how to confirm and manage the sites they’re following without needing to register at WordPress.com. http://en.support.wordpress.com/following/
Staff added social media followers you have on platforms that you have turned on under "Publicize." So the total number of followers displayed by the Follow Blog Widget includes blog followers, FB, and Twitter followers. I suppose it's the total number of followers in one sense, but it's not the total number of blog followers so it's misleading.
Yes we can contact Staff http://en.support.wordpress.com/contact/ Note: When we create a support ticket by contacting Staff it’s important to understand they have a backlog. They provide support for 31 million and they deal with the support tickets with the earliest dates first. So if we contact them more than once of the same issue the date moves forward and it takes longer to get help.
