Hand picking what may be potentially irrelevant to a subject or harmful to be read by a community, and hence banning it is censorship by definition.
And one does not need to be personally too involved in the embarrassment that Goodreads has apparently turned to in order to realize that this is exactly what is being applied by Goodreads staff as of late: CENSORSHIP.
In this respect*, this book gives a very comprehensive analysis of the facts on behalf of the reviewers that have been affected by the new PRO-CENSORSHIP policy that has been introduced at Goodreads. It is very clear, extremely well written and documented and I would highly recommend it to anyone with a brain.
*Ambitious attempt to contextualise first two sentences, in order to avoid unnecessary and incorrect assumptions for review to be CENSORED as potentially off-topic.
