We have made it so you have to apply for creative due to people joining just to try and lag the server or other things that are not right. In order to ensure the players are actually going to play we ask that before they get access they play the other gamemodes for at least a few days. Since you just got unbanned it does not instill a lot of trust in you yet. Please play the other gamemodes first. You may put in another application in a week after getting more time in on the server. For now your request is denied.
