I have gone on this server many times in the past. Granted, I have not been on it much as of the past few weeks, but I think we need to look at the big picture here.
Communicate.
Half of the problems people have can easily be resolved through communicating with the administration and the host of this server. As you saw from a couple posts up, Kreon is super reasonable. If you were banned or didn't agree with something, did you even make an effort to communicate with him/ get both sides of the story before freaking out? (I'm saying this to everyone, not specifically the OP). It is just the mature thing to do.
If you PM him or another admin, they will explain their reasoning behind something, or take action/ fix something. It is as simple as that. I know some of you are going to say that you are banned for something before you can explain XYZ... but again, just make an effort to PM the person if it was something stupid and you enjoyed playing on the server.
Finally, if you don't enjoy the server, just don't play. This is Blockland. It is a video game. On top of that, Kreon rarely gives perma bans... you can always go back when the time is up on your ban.
