Wow, that’s annoying. My account got banned two days after I started using another client.

They never actually told me why I was banned, but the funny part about being banned on Discord is that they simply deny you access to your account.
The account still existed, all the chats were still there, I just couldn’t login anymore.

So I went GPDR yada yada and told them to delete it. Though you can be sure they don’t honor that and keep a copy of everything, because no court seems to care that LeGitiMatE InTEreSt has no legal basis whatsoever.
