To be clear
Both words that you listed in quotes at your Q2 are not allowed
In general any racial slur is not allowed in any context
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.
