First off, calling other fans names is not allowed.
Second, David, to further clarify what I said earlier in this topic, you may not provide further information about the identity of the person or persons you have publicly accused of harassment or slander: No sex, name, location, position, occupation, etc. The Forums welcome DS-related discussions (we're thrilled that fans find this a safe place to share their thoughts!), but not at the risk of liability.
if the behavior becomes so abusive and vindictive that it drives good people away for good, then yes, the bad folks
should be given a choice:
change or leave.
Well, I respectfully disagree. Behavior between adults that leads to hurt feelings is terrible, but it's not a security issue, and I don't believe that fan politics should be the Festival's concern.
