Answer:
On the appeal:
It’s an unsafe and dangerous assumption to make. If your assumption is that racist behaviour is allowed by default, then fundamentally, your core values are at odds with this server.
You’re saying that the ban made against racist behaviour, which is outlined in the rules as an immediate ban, is not just?
Your case rests on two parts. The first, that you were not aware of the rules (in this case, the ones broken) and the second, that you did not perform the act that lead to the ban.
Claim 1
Not knowing the rules is not a reason neither a justification to having broken them. Usually, this ban appeal process ensures that people know the rules before they are allowed back into the server, this can in many cases be enough. However in this scenario, racist behaviour in a public chat is not something that can be reasonably expected as allowed, regardless of having read any rules or not. This points to a problem that is not resolvable by just getting you to reading the rules.
Claim 2
You can claim that it wasn’t you, but it being you or not is irrelevant. The ban applies either way because you are here, banned. People could claim it wasn’t them for every ban; it would solve nothing each time. Pointing a finger at someone else doesn’t resolve the problem. It’s also not convincing that the problem won’t come up again considering it has happened in the first place.
