hey jonas,
you can enable/disable this in the ACL section of your easyblog backend.
as example if you don't want to allow (show) this for the joomla usergroup "registered" you can go to your easyblog backend -> acl -> then click on "registered"
in the list you'll find an option called "Feature Blog Post" - set this to NO and the option will disappear.
hope that helps and have a nice day
