Hi,
The server was experiencing a huge influx of OOC in IC rulebreaks, with numerous staff announcements made that the punishment for doing so would continue to increase. It was made aware to the players of the server that the next punishment after the 30 minute mutes would likely be a worse punishment.
When you decided to then post an OOC in IC advertisement, a deliberate choice to spread it to the widest possible playerbase, I was told to issue a ban. The ban length was determined by myself with some advice from other staff members.
Whilst in the sit you asked "What can you actually do about it" - I assume because you believed you could get away with a mute and feel no real consequence for your actions.
At the end of the day you knowingly broke the rules of the server, using OOC in an IC channel to harass a staff member and you were confident you would not be punished duly.
There is no specific guidance on what is and isn't a suitable punishment, but I had sought advice and was recommended to issue the ban. I believe the ban is justified and your actions in the forums and server discord further highlight your lack of remorse, understanding or care about your actions.
I believe Pendred has said enough on the other aspects of this case and I will not need to repeat what he has said to everyone in here.
Good luck on your appeal
