First of all, there were no official servers in 1.1. Second of all, you have not at all told us what this continuing mistreatment is about, so I doubt we can influence that in any way. We can only comment on this single, poor case you have.
Okay, if there were no >official< 1.1 servers there certainly were servers which were admin'd by official developers, etc - which may have been a better choice of words. I do apologise for the symantics.
The single poor case I have is reasonably well documented by the admin who was present for part of the time (of which I was not). I did not ask for your comment on this "single, poor case" however I am happy you contributed. As I have left all but the forums, I feel no need to provide further evidence of other examples and am only still on the forums out of sense of good natured arguement and a slight loyalty to furthering the cause of free software under the right circumstances.
I doubt anyone can read your mind here, so that's the only case we can comment on. Other "lacks of admin responsibility" and "admin abuse" are mere speculation and we don't even know if they existed.
No, official servers are official servers. There were no servers with the official status before the release of 1.2 GPP and the matters that happened there are entirely different things and I ask you to leave them out from your view of point. Those servers are privately-run, it's like entering another person's home, they decide the rules and have the right to ban you on sight if they wish. The official servers on the other hand have reasonable rules and they are well-policed. We have no power over any misdeeds happening on some other server but on the official servers we are providing everyone a nice environment to enjoy the game.
All in all, some good advices: Play on the official servers, make a "reputation" like janev said and you don't ever have to bother yourself with griefers, admin abuse and so on. If there ever happens to be problems, hop to IRC and ask an admin to resolve the matter. These make the "continued mistreatment" go away. It's a mighty good game, the new version.
