How much personal information is necessary to close a bug?

[Lex Hider]

Hi,
I was wanting to do some bug triage for fedora.
I checked out the list of NEW bugs for one of my favourite apps: amarok.
There seemed a pretty obvious bug that could now be closed:
https://bugzilla.redhat.com/show_bug.cgi?id=248625

I tried to close it and found I didn't have the privileges to do so.
I asked on #fedora-devel and was pointed to the triage team wiki page
and that I need a Fedora Account.

Apparently to open a Fedora account I need to give my postal address and
telephone number. Why is it necessary to give this personal information
just to close a bug?

Contrast to other projects I have contributed to where some realizes you
know what you are doing or get sick of you pestering to close bugs on
your behalf and give you the relevant privileges.

Here's an example of my bug closing credentials:
