Sitewide privacy options

Hello,
I am using https://premium.wpmudev.org/project/sitewide-privacy-options-for-wordpress-mu and it works as it should except for one thing;

The post being made in a private blog are shown in site wide activity (for example http://skolbloggen.se/activity/feed).

Thats bad, very bad if you ask my users. Have I made something wrong or is it a bug?
