Yes, I know, my questions where rather rhetorical. :) Hulk Robot reports
are ridiculous, in my opinion.

The tool (checkpatch) used to detect warning is public, so from
community perspective this does not differ from John Smith sending a fix
for a checkpatch issue.
However I do not expect tags like:
  From: John Smith
  ...
  Reported-by: John Smith
  Signed-off-by: John Smith

How does it look? Neither I expect some unknown, hidden, secret reports
like:
  Reported-by: foo bar
  Signed-off-by: John Smith

Simply the credit of running the tool (e.g. checkpatch) is already in
the patch authorship. The Reported-by is for crediting additional work
related to the report.

No report, no credit. Otherwise the value of Reported-by cease to exist...

Best regards,
Krzysztof
