Facebook automatically publishing Page posts under your name.

Ed Bott: "If you actively share a link, a post, or a photo, you expect that shared item to go out to your friends immediately. In this case, however, the posts are going out under your name because at some point in the past (in some cases in the distant past) you visited a page and clicked Like.
