Because a lot of the yukkuri fanon is shaped by the discussions that go on in the yukkuri threads on 2chan. Sometimes the comics aren't even posted in the right order here.
Even then its impossible to post the discussions. We have enough problems getting comics translated, there's no way a 30 comment discussion can be capped and posted, unless there's a way to somehow archive 2ch's threads and then run it through babelfish.
As for the comic thing... I'm aware of that problem, which is why I was wondering about the parent-child relation for comics a while back.
