remove social sharing

We are trying to remove all social sharing to facebook, twitter, pinterest, etc.
We're unable to figure it out. Any suggestions?

I suppose I should let you know it's a 7.1.3 site.

Well, I don't know if what I did was correct, but I removed from sys_objects_actions in the database the script link for each.

Now I have no share button in the action block on each individual page.
