But noone cared for them. They there that rare, the people of /a/ barely saw them.
Howether, the big moot got angry with those strangers. He didn't like them. From time to time he banhammered some of them. He felt fine that way.
The People of /a/ saw bans and wondered, they now realised, that very rarely pornpictures were posted. Some of /a/'s people ran to moot and whined. That made moot so angry he not just banned the people, he divided /a/ into /a/ and /jp/. The Big Wall Berlin had was revived and countless people of /a/ were very very sad.
