I really don't understand this part at all. How is anyone being "blocked"?
The reason for a lot of the RP and stories, is that there is a fairly large group of young people on this site, who have active (some might say over-active) imaginations. They generally have interest in poultry of some type, but they enjoy just "socializing" with each other, as well. There are lots of threads that aren't particularly chicken related, that adults post as well - this forum and Family Life are popular areas where the threads are hardly ever chicken-related.
Because New Posts covers the entire forum, it will naturally contain a certain amount of material that won't interest you. This is such a diverse community, with such a variety of interests, it's inevitable that not everything would be about raising or eating ducks and chickens.Do you want to read threads about, say, emus or peafowl? Even if the kids weren't posting their games, there are still people that would be chatting about their other hobbies, sharing their personal joys and sorrows, or discussing recent news stories. Every forum that I have ever been on involves an area for that, as well as sub-forums that are dedicated to specific aspects that are so narrow in their scope, some members are bound to not be interested in them. Why single out the kids?
