I think everything has been said, you did break a rule obviously.
If you're new to the Server you'll probably get warned for little things again until you get to know the rules, it just happens.
If you talk nicely to the admins that are handling these reports, you might just talk it out.
Just leaving the server or being disrespectful won't get you anywhere - That's common sense.
Feel free to come back and play on the Server, these Admins are just doing their Job and I'm 100% sure It's nothing personally.
Have fun.
