I manged to find a solution myself. While it’s via a plugin called “Simply Excluded”, it helped with the main mission as well as give me some additional options.
I thought it was something like machines copying the text, not humans.
Oh well. I guess this is not too useful.
Maybe if I provide an example:
http://www.illdoctrine.com/
On the left column, he has a section called “bonus features”. Which basically is like another blog, except it’s not stuff within the main blog.
Is this possible with WordPress and how?
