For nm.debian.org, at 2023-01-08: Ileana Dumitrescu has helped me on giac's packaging.
For this past work, Ileana Dumitrescu sent mails using the email address email@example.com
which is the one they're using on nm.debian.org, and they signed their work using a GPG key with
fingerprint FA26 CA78 4BE1 8892 7F22 B99F 6570 EA01 146F 7354.
I've made sure that they are able to decrypt encrypted messages sent to this key
and that they're able to sign messages with the same key.
I'm pretty convinced Ileana Dumitrescu is the rightful owner of both the above email address
and the corresponding GPG key.
