Wordpress is the most popular and free content management system. *We can design beautiful websites with wordpress and add content pages easily without knowing bulk code also.
After installing wordpress website we will get spam comments excessively. *In order to avoid those comments we can install *many themes. But in my experience I found that 'disable comments' plugin is secured and safe.*
After installing you just make 'disable comments everywhere'. It is free and secure plugin in my experience.
If you have any doubts or views on wordpress please share.
