Google+ seems to be appropriating shared Google Reader items

I use google reader and I use have a google alert for my name. Most of the time I learn a lot about a high school basketball player in kentucky, ie not me, Today though I was alerted about a story I shared in may, about Childish Gambino, but instead of it being a google reader share it was a google+ share. I don’t mind that my google reader stuff is on google plus, but I am sure that some people might be concerned that that didn’t purposefully choose to share things like google reader on google+.
