How to get out of this forum / delete acccount?

🔮 Meta

This thing (help.nextcloud.com) sends me mails I do not want. It does not make it easy/obvious to stop all of them. So consequently I wanted to outright delete my account. That functionality cannot be discovered either.

What gives?!

For the e-mails, there has been a topic about, not sure if you have seen it and if it helped you:

We can anonymize your account if your wish (Delete my User Account from help.nextcloud.com).

Please anonymize my account…

Thanks.
