They honestly may be, I think they are all proxy accounts owned by the same person, unless I am wrong. They will afk for days and just stand there. I would understand if it was just one person dancing afk in limsa because they could be chatting, but have no clue about the jades. Here is a picture. I could be wrong in all of this, but dualboxing multiple afk accounts seems a bit selfish when people are having trouble staying logged in during duties and getting kicked consistently due to server load.
