Yes. Always involve a human check before sending to specific individuals.

Of course. Therefore, we need people who play "frontend" role and people
who play "backend" role. The former (Alice in the example above) is a
"dispatcher" who interprets syzbot reports and decides whom to notify.
Currently syzbot is making decisions based on MAINTAINERS file. But
you are missing that persons listed there are generally too busy to
look at details. Reports which do not tell "what is happening" and
"why it is happening" at a glance are not useful for them. If I recall
correctly, many weeks ago, you were discussing with Linus regarding
what should be done before reporting (e.g. bisect).

Only "frontend" people will look at reports from syzbot, and
"backend" people will triage reports from "frontend" people.

It is impossible for all kernel developers to read all mails.
That's why we need to use roles, like I said that I have worked at a
support center and experienced both "frontend" role and "backend" role.

We can do this work if we use roles. And I'm rather working as "frontend".
For example, I interpreted a report from syzbot and forwarded to authors
which caused that bug as
http://lkml.kernel.org/r/a6e8d929-3765-ad70...@I-love.SAKURA.ne.jp .

If we do want to send a report automatically, it should be sent to only
one mailing list. That would be either LKML or syzbot specific one
(for allowing people to find using Google search).

I disagree. Mails sent to maintainers are seldom useful; again, they are
too busy to examine the bugs. Mails sent to authors which caused that bug
will be useful. Thus, sending to mailing list for Google search would be
fine, but sending to auto-generated individuals is bad.

Are they reading semi-relevant emails?
I don't read threads which are not actionable for me.

As a "frontend" people, what I want is not a bug tracking system like Bugzilla.
What I want is a column for holding free-text memo (like "sticky", or "Google
Spreadsheet") rather than structures for choosing from checkbox/combobox (for
finding from many thousands of bugs).
The "backend" people can use Bugzilla etc. if the bug is complicated enough to
require a bug tracking system. There are too many bugs left unnoticed in bug
tracking systems. I don't think that registering to bug tracking systems from
the beginning is a good choice. More trivial bugs, more difficult to manage
important bugs.
