Are guilds allowed to sell guild invites?

No, they charge a sub to join their guild. Which may or may not be against the rules but nobody can seem to determine.

So, where and how is the ā€œfeeā€ collected?

Do you pay gold in-game to get a guild invite?

Do you pay a sub to join their Discord, then they invite Discord members to the guild in-game?

Patreon.

With US $

I remember someone saying it goes against Blizzardā€™s terms, though I donā€™t know if thatā€™s true. I still use the Discord from time to time and I have no interest in joining their guild. I figure if I want to raid on a set schedule, there are plenty of beginner guilds out there I can hit up or I can join a community.

Also, wasnā€™t the controversy about WME using the Ibelin documentary about a dead WoW player to sell guild access?

What about having to do an in-person interview, flying across the country, to get in the guild?
