So as a member of the Lore Team, we try to get as close as possible without creating a replica! It's essential to think of Potterworld as much more than Harry Potter; we have unique towns, quests, items, and more. It would cost a fortune, and as Joe_Magus concisely remarked, server administrators would have to sell their very souls. Additionally, there's a very slim chance that J.K. Rowling/Warner Bros. would even agree. The sever has built upon Harry Potter lore and evolved into its own entity. One of the main issues is that we do have a store, and thus are making money from the server. It is not in accordance with international laws to profit off of someone else's work! In addition, many names do not have a lore name, which is especially noticeable in classes. This is because classes (especially ones such as Magical Cuisine, Magical Debate, etc.) are similar to "fan discussions" of characters or events from the Wizarding World, and thus copyright laws do not apply. I believe that the Potterworld towns are incredibly well made, and the subject of hard and fantastic work. To get rid of them would be unthinkable, in my opinion! I also believe that not being able to say You Know Who's name is a fun, immersive Easter egg, rather than a restriction. I do understand your preference for the terms that we all know and love, or even grew up with, but for now it is simply impractical. As luckiestblock so politely pointed out, it would definitely place an unwanted restriction on creativity, which is something I personally view as extremely detrimental, considering my current position.
