I only have a single moderator/linksack holder in my linkshell group. The player is a real life friend. I'm never adding more moderators. The point of a linkshell is to separate the players you like from everyone else. I don't invite just anyone to my linkshell. The first requirement is that you be on my friend's list for one thing. My linkshell, at least, is like a top tier friend's list. Anyone who requests it can be in my friend's list, but not anyone can be in my linkshell. Keep in mind that whenever you equip a link item, you see all the dialogue of everyone else chatting linkshell mode. If you don't want to be bombarded with spam, be careful who you invite. I only have 6 members in my linkshell group at the moment, and I'm not rushing to fill out my numbers. Quality over quantity is probably a good mantra here. Anyhow, that's my 3 cents. Hope it helps.
