Currently this verifier will post an informative error if the author has not signed CLA, instead of rejecting the CL.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

Sheng, you need to add "LOG=N" into description for V8 CLs. This basically says
that you don't want this change to show up in V8 Changelist for the next release
(not sure where it appears).

Since this check-in I got reports from external contributors which companies
have signed a corporate CLA that they receive a message like in
https://codereview.chromium.org/1038363002. Do you have clue what's wrong here?
