Don’t try and test it next time, you can read the rules since they cover the topic. Even if just putting a racial slur feels like it should be common sense of “don’t do it.”
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.
