Everyone has permissions

I am looking to setup a membership on my site and in testing I see that when a user registers, which they are put in the registered users group they for some reason have instant access to write a blog post? First off why is this even a default option and what do I need to do to disable this weird feature?

I have went into the Global Configuration and down to EasyBlog and it is showing registered users do not have permissions. Yet in the EasyBlog Authors section of the component that is not the case and I have registered users listed as authors. I dont want any of these registered users to have permission to write on my blog but setting up Joomla ACL is by itself over the top complicated and from what I am reading in the EasyBlog documentation you guys are not making it any easier to get to grips with...
