On the E3 Digital Venue domain,
https://e3expo-portal.com, there is a JavaScript file (main.6fd9bebd.chunk.js) containing a list of banned words from the messaging functionality of the virtual booths (and probably other areas where users can submit messages). Most of these words are offensive/profane and of a sexual nature (which I won't link directly to the file). Other words aren't very offensive although may be used offensively in certain contexts. And some words I can't really find a good reason for being included in the list. Some politically oriented words are included in the list, most of them oriented towards far-right politics. Below is a selection of these words (presented as in the JS file):
Religion
alah, allah, azazel, christ, god, jew, jew!, jewed, jewish, lucifer, koran, nimrod, omfg, omg, qu'ran, quran, surah
Geography, nationality
canada, canadian
Political
