Indeed! I think it's because on JF is much more community-based than LJ? Because most people don't have their main journaling home here. So if it were on LJ many people would just post the links to their personal journals, and the issue wouldn't come up as much.

F_l seems to be a huge point of contention, though, and I don't think the fault is entirely that of the posters who post things that annoy other people. After all, if a post about some other minor Twilight aspect was accepted, then people will just think it is acceptable to post whatever about Twilight. The fact that no one (including me) seems to protest only contributes to the problem...)

Similarly, there seems to be a lot of confusion about which topics are too dark or disturbing: some people say that it's just bad to post things which are upsetting, others say it is okay, just as long as they are fandom-related.
