First, I think moderation action was warranted.

Second, an act by a company rep telling another FT'er that he's violating SPG terms and conditions is an implicit (though unintended) escalation due to the assumption (unwarranted in this case) of adverse impact through official action.

Thus my opinion is that the wise thing for all involved is to back away from the potential conflict. It's not doing anyone any good for William to involve himself with CC any more than it would be for any of the AA employees on FT:AA to involve themselves with CC.
