I'm a solo dev. In order to successfully manage and create this game, I have to prioritize features & bugs and manage my time very carefully. Occasionally players will accidentally or purposefully do things in game or out of game that creates a situation where I have to do work that doesn't benefit the community or the game. These situations can sometimes be hard to predict, but generally if it was an accident and you aren't a jerk to me in your correspondence, then it is resolved quickly.
Short bans are sometimes used as warnings, or to defuse a situation. Contact email@example.com to clarify. I generally sleep from the hours of 10p - 7a pacific, but I try not to ban players at a time where I can't respond to their concerns.
Repeated instances of this kind are judged harshly.
