The title says it all to be completely honest. If I want to save something I've created "privately", it should stay that way, yet I barely ever publish anything, and I still see my "private" saves getting views/up-votes. I don't know how people are getting their hands on my save ID's, but it's starting to get annoying. If I'm missing something, or If I'm just completely wrong, please tell me, but as far as I know, people shouldn't be able to see my "private" saves.
Well, there's nothing to stop people finding unpublished saves by loading random save IDs...
However, note that all saves, including unpublished ones, receive an automatic upvote from the person who created them (i.e. you). And I suspect the view counter probably increases each time you look at one of your own saves.
