Cant join HOG discord

I remember a while back I joined the HOG Discord when I saw it on the website and I didn't really say anything or do anything in the HOG discord and stayed pretty inactive. After a couple of months I was looking through all the different PR related discords I was in and I couldn't find the HOG discord so I assumed I was kicked. I asked a friend to invite me to the server but the invite was invalid and I couldn't join even though the invite he sent me wasn't temporary. So I was wondering if I got banned from the HOG discord and if I got banned from it what was the reason for my ban.

What is your discord name and ID

Ender#8979

You were banned for Racism,
We do not tolerate any racism on our server!!

How was I being racist and is there a way I can get unbanned
