Nope. Many comments from green accounts get flagged and then auto-killed unless vouched for.

This is a green account that got auto-killed: https://news.ycombinator.com/item?id=48304852

This is a green account where someone used the "flag" button to kill it: https://news.ycombinator.com/item?id=48262928

Note how the former only says [dead] while the latter is [flagged] [dead].

The spam filter does both. You can verify for yourself that flagging a comment most of the time is not enough to kill it.

[yorwba]

The spam filter influences the number of times a comment needs to be flagged before it becomes [flagged] and gets killed, but if it says [flagged], someone used the "flag" button at least once. Sometimes just downvoting a spam comment is enough to kill it; those just get marked [dead] and not [flagged].

To you and other commenters who are missing it ...

No green accounts involved here.

That doesn't mean the spam filter isn't culpable here - esychology is still a relatively new account.
