to simplify,
it is natural that the post 's copyright belongs to the one who writes it and thence he has every right to set whatever he thinks fit .
it's really ridiculous to complain why the writer doesn't want someone to read it .
I really don't see any supportive reason to lodge this argument !
small circle exists everywhere , in your family. company, community, school, etc .
nothing special that it exists in forum !
But still I don't see any relation between "small circle" and "setting points" to read post.
they are not the same thing .
