Getting upset by a user asking a group of people gathered together specifically for talking about books for recommendations of a similar style to a book they like is pretty weird. What else are we supposed to talk about? This community is called books, the post is about books, the comments are about books. Seems to be pretty on topic to me.
When torrenting you client should be “Connectable” which means fully accessible from others. You can use the guides others have posted to achieve that but basically, an unconnectable client can still seed to those who are connectable, but two unconnectable clients cant connect to each other. Or at least this is how it has been described to me by a private tracker.
