Community Account Banned

When I log in with my usual Apple ID, I'm told my account is banned.

I would expect that when a forum account gets banned, then the user would receive an email about that.

I do not know why, I have been a loyal customer of Apple for years.

Being a customer or not, has no impact on it at all. I think it would be about what was posted on these community forums using that account. About something that was said, or how it was said. Not adhering to the Terms of Use. For more inquiries, please contact the staff at the email address listed in the Terms of Use for this forum site, with all the necessary details for them to find the relevant user history.
