How to delete Bugzilla account

How to delete a Bugzilla account that is not needed, and has no relevant bug reports?

My meta tag may be incorrect, if so which should I use?

I remember reading IRC discussion, when a developer wanted to remove own bugzilla account, and was told it’s not possible, but it was possible to edit it and change email to a fake one (effectively making it not functional). Please also change the displayed name if you decide to do so, e.g. add “(retired)” to indicate to others that the account is not used anymore.
