"THEY" being the moderators. IOW the moderators posted messages on the crevo threads alerting participants that attention was being paid to these threads and that the moderators were determined to resolve the problem with flame wars.
Which again is why g3k's behavior was so bizarre and over the top. The admin bent over backward warning him and trying to AVOID banning him. The moderators had already banned the main troublemakers, led by a poster named "ALS", who (seemed to be) working in a little cabal that did not include g3K. But gore3000 (behaved as if he) was determined to get banned.
