Easyblog frontend blog creation

Hi,
I want to disable the front-end blog creation.
I went to ES > Settings >> Layout and disabled everything..

https://nimbus.everhelper.me/client/notes/share/149260/hrhT7LCgKbMpgyHtaCNU9kJmdwaTDlMR/

However if the spammer knows the url, they are still able to write a post.

http://www.mysite.com/blog/dashboard/write.html

If the dashboard is disabled, this functionality should be disabled as well not just hide?

Another question:

Is there an option to moderate each post before publishing them?

I am using the latest version of ES and Joomla.

Thank you and looking forward to your reply.
