How to fix indexing and spam problems from my WP site?

I received this message from Google console "Major spam problems persist on https://www.vogon.us/

After reviewing your reconsideration request, Google still believes that https://www.vogon.us/ violates Google Webmaster Guidelines. Therefore, we have not reincluded the offending pages back in our search results in order to maintain a quality experience for users. Only submit a new reconsideration request after you have made the necessary changes to your content.

Fix this problem now:: 1
