I have no administrative power to find his IP (which he claims to change every now and then anyway), but his usual tank name is "Pat Labor has 3 Nipples!"
The hack goes like this: At specification, he is able to "hop" (change his coordinates) over another tank, where he uses his pre-equipped Shock Wave flag. He's real smart-ass, too, calling the others in the server "weak and worthless."
I've been seeing this guy do this for about a year now, and it's starting to get on my nerves. I've filed a couple reports with individual servers, but what can that really do? I want this guy's IP found and blocked!
He's one of the old-time faithful troublemakers. His various IPs are banned on most servers but of course not on all of them. With the next release, you'll likely be seeing a lot less of players like that as there is a new global bans system that will be in the next release. The system will allow the devs to remove extreme trouble-makers like that from most all of the public servers on demand. While server operators will be able to disable the global bans (or provide exemptions), the hope is that most will not so that such blatent disregard for other people's enjoyment of the game becomes less disruptive. This will put some heavier penalties on the cheaters and @ssclowns on servers that don't allow or want that.
I do appreciate the idea of a global blacklist for all servers.
There is just one thing you should all keep in mind. Administrators are hopefully acting differently on different servers. The responsibility that comes with feeding addresses to a global blacklist is, though, something that needs to be considerated thoroughly. Normally, such a decision is to be discussed with more of the people involved, before such a ban is enacted.
Devising policies or organizing discussion groups is certainly not what anyone is after, when he establishes a new game server in the net.
So, global blacklists might as well cause more annoyance on both ends, help to establish worse "dictatorships" or create simple chaos...
But I am more curious than frightened ;-)
Right now, the ability to add or remove entries from the global bans list is solely in the hands of the folks that continue the game's development -- the developers. Changes to the list and the list itself is made very public, and modifications are instantly announced recording exactly who made what changes. That said, additions should not be made except in obvious cases of abuse after careful consideration of the disruption(s). The individual generally will need to be disrupting the gameplay on more than one public server and the "level and form" of disruption certainly matter as well.
Server operators will likewise have the ability to completely opt-out of this list or provide specific exemptions from the list on their server. Nobody is being forced to accept the banlist -- it'll just be the default. There are more details on bzbb.bzflag.org for folks interested in the discussion points that have come up.
