I'd agree they make contacting individual people difficult, but I can see why they have done it given the state of the RMT spam and what lengths they go to. On the other hand, a linkshell directory would be a boon and help people find people who are like-minded or doing similar content, interested in the same things, etc. I'd like to join some linkshells on Tonberry, like people hooking up for potd 200 runs for instance, or an english speaking general social linkshell - I assume such things exist, but no way to know. And if you start one, there's no decent way to get others involved.
