Anonymization removes all references to your email, username/password, and any other personal information (including IP history) from your account. It is irreversible, and you cannot use the account afterward.
It allows your posts to stay (thereby preventing the disruption of old conversations), without including any identifying data. People can request it for any reason, we don’t require an explanation, but I do tend to make it very clear that the act cannot be reversed (because we’ve lost all identifying data that would prove ownership of an account).
