I think it would honestly be more helpful in LS communities considering there is such a limited number of people that can join one LS. With a free company, you have 512 slots to fill, with a LS you only get 128. That's 4 times the amount you get in a LS, so a LS is more likely to fill with inactive people quicker than a FC ever would. Linkshell's are rather restrictive as it is, and making sure you can provide a social channel to active members is something that's very important to some linkshells leaders. While linkshells like Hunt LS's can easily kick inactive players, some communities that's not an option since it's a channel that they often speak in and don't want to constantly hunt just to chat with people in that same community.
