Not a staff restriction, its a ban.

Even if you're not the one using the word itself, it should never be brought into the server.
Rule 15 states | Never harass and/or disrespect other players/staff.
Gaminglight does not tolerate bullying or targeting based on race, gender, sexuality, or other identities, nor racial slurs or anything that can be deemed offensive. Gaminglight has a zero-tolerance policy towards this type of conduct.
In the way you were using the word, it does not seem like targeting people for there race. HOWEVER it could still be deemed offensive, as the word itself has that history behind it.
