This seems unclear. Admins were banned from Discord for inviting people to your discord or were banned for inviting active members of your discord community to your WoW server? Is the WoW server a bootleg? I'm not a WoW player so not sure what's out there, but I wouldn't be surprised if Discord-the-company was involved in something that might be considered anti-piracy actions. The other question would be if they were doing something that would be detected as spamming, either for your discord community or the game. If the invites were sent via DM but were the only DM messaging between the admins and users they may well have tripped an automatic detection.
