mlspamcb@noci.xs4all.nl has no bugzilla account.
As proxy-maintainers should be responsible for its proxies... Can you email him about whether he is still interested in maintaining this package, and notify that him creating a bugzilla account is required to continue doing that. I've never had any contact with this user, and so it'd be best to be initiated by and handled by the proxy-maintainers team.

Nico Baggus, I changed your contact to mlspamcb AT noci.work as it is still in bugzilla. Remember, if you change the bugzilla contact someday, change your contact in the metadata too, please.
