Because people tend to keep the /sh and /say channels spammed with RP chat. It seems like they're really desperate for attention, but hey, it's their choice. It's not as common on Gilgamesh, but it's super annoying to see your chat box spammed with people RPing. Its enough to make me want to turn off my /say and /sh channels completely.
Just my opinion, however. I don't expect everyone else to share my views.
