Badplayer showed up for DL a few hours ago. Also I have to say a public blacklist is just going to ruin the community and really drive away new players. As someone stated before get a TS server and ask everyone who is going to show up to join the server. That's what we, DL, did. People signed on, we roll called and whoever showed up was secured a spot, those who didn't we assumed weren't going to make it. A few DL players missed the roll call and thus when they joined didn't get to play but such is life, they learned and now next time they'll be there early. It worked out great for us. We didn't get mad at anyone. There was no banlist/blacklist that we had to make and revise depending on persons reason for missing the battle. The most annoying thing we faced was hearing the endless "user has left the channel" prompt from TS.
Besides how can you trust a public blacklist? I may hate someone and simply add them as part of a list.
