Roughly half of messages sent to logstash are from AbuseFilter writing to the StashEdit log bucket. That cause logs to be emitted for each filterAction calls.
The info log has been added by e91939fb3fdc93842ec64541302a2157a377b440 for T137698.
It does not seem to serve much purpose in production nowadays. Can we change them to debug and raise production login for StashEdit from debug to info?
