Considering the number of players who had previously joined, contributed nothing except say a slur, and then leave, I personally think it’s fine since it’s not allowed, but… eh, whatever. You get the gist from the ban, it’s not allowed. You owned up to it, you understand.
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.
