One time we joined a system server, and an alter started proxying. His displayname was basically [his name] some symbols then [Korean petname]. It was matching with his girlfriend who was Korean, and called him that.
Immediately one of the mods made a ticket to discuss it with us and accused us of cultural appropriation and using closed culture names. Keep in mind they did not even know our race at the time and assuming we're white is really weird, and they clearly didn't even know Korean as it wasnt a name (although I understand assuming it was a name it was still weird)
We explained it wasn't his name nor were we using it as a name, it just matched his gf proxy and was a petname. They still insisted he shouldn't be able to use it, and that we were being racist for it. We tried explain for a little longer but they threatened to kick us over it and we just left.
That's just....no words
Let's remember there's a difference between cultural appropriation and using the nickname your partner gives
