I saw a strange and abrasive comment in one of my bugs today: https://bugs.gentoo.org/711778#c6 The email is a Guerilla Mail address (https://www.guerrillamail.com/) used for disposable email addresses. Can we block sign ups from services like this?
We can block individual domains, but will generally NOT do so, because it's trivially to just run disposable mail on another domain and there are in fact services that do so already, with pre-aged domains. I have locked the account in question, please notify us of further cases where you see spam drive-by commenting like this.
