I have a new circle and you're probably in it. But if you don't want to be in it, just let me know and I'll try to remove you. What is this circle you ask? Why it's the circle that gets to see my Plus1 Spam of course.
Following these directions https://support.google.com/plus/answer/1047397?hl=en&ref_topic=1207011 I added all my relevant people to that circle and limmited the Plus1 sharing to that circle. In theory, if you are not in that circle, you want see which posts I give a plus1 to.
Since you can't control it for yourself, I've set it up so I can be respectful of your preference despite Google's failure to give you that option. Also note that the computer instructions fall short as I could not see the tab mention. So I did this via mobile app.
If you would like to be added or excluded from this circle, just let me know and I'll do my best.
