I find it rather annoying when I'm getting spammed by some RMT user while I'm in the middle of a leve, shopping on the market, or whatever, then when I attempt to blacklist them... 'Lo and behold, it says it can't find the name because they're suddenly unavailable. We should be able to blacklist these people at any given time. You may want to plan ahead as well since your friend just informed you of one that he got a message from an hour ago, but you're unable to blacklist them because they're offline.

Secondly... Is it really necessary for us to wait until someone is online before sending them a friend request? It took days before a friend and I could actually get online at the same time just so I could send him a friend request and mail him something to help him get started. Would it have been so hard to simply make an offline friend request into a mail format so they could access it next time they sign on and choose to accept or decline?
