Keep an eye out for the kick message in the future, the server always shows a message like I showed previously (but with a different part after reason). If you’re playing something on the server, you might notice that things start to break due to being disconnected, e.g. you can break things in protected regions, or players stand still or just run off in one direction even if it wouldn’t make sense. If that happens, check chat to see if you something comes up that disconnected you for whatever reason, like a kick message.
Can you read the rules and quote the rule(s) you broke? Do this in a new reply, don’t edit your appeal. If you do not know how to quote the rules, read the guide How to quote the rules.
If you do not identify the right rule(s) that you broke or you do not know which ones you broke, I can make it clear.
