If it was caused by a bug they wouldn't have told him "you have no future with oracle" and that he couldn't create a new account -- they would have just created a new account, apologized, and given him a few months credit.
If that account was nuked for disobeying the terms of service, I would've somehow understood the reason. Most likely because some CSAM was uploaded which was federated to my / Oracle's servers.
However, that server and account wasn't deleted. Only my account, which simply had a Nextcloud instance on it, was deleted in this strange way. Now, technically you could also host horrible stuff on Nextcloud, however I am VERY certain this isn't the case. Additionally, I think they'd need to tell me if that was the reason?
Everything about this is so strange.
