That’s not what we want, is it?

Mick, to a degree, I think you’re correct. We don’t want to be feeding trolls.
OTOH, could an angry response be considered food for a troll? If trolls enter a forum seeking to cause upset, and the forum responds angrily, doesn’t that validate the troll’s tactic and reward the effort?
And what about lurkers and pro-MLMers who read this board and see how we react to a contrary opinion, or to those who seek to mislead the forum – or out-and-out lie to us? Does it reflect well on the forum to react with anger? Or do we simply justify all the criticisms that are leveled on ex-MLMers as “bitter” and “unable to get over it?”
Don’t get me wrong, Mick, I’m NOT saying you’re wrong for pointing out lies and discrepancies. I welcome that. That’s much of the purpose of this forum: calling out the liars and hypocrites that permeate the MLM industry.
I’m not condemning anything. I’m questioning the way we respond to those who may be “future survivors,” in need of a forum such as this one some day. Remember that people involved in MLM frequently tell lies because tactics such as those are taught and encouraged in MLM.
(Remember the “Curiosity Approach?”) Whether she was lying or parroting, Carrie will leave the forum feeling that her visit here validated her involvement in MLM.

Don’t feed the troll is a good motto

with respect to all – and with the understanding that this is PW’s sandbox and he sets the rules and I will stick to them…

This is the wrong way to handle trolls. Allowing them into any forum – especially survivors forums – is to guarantee upset.

The analogy you used in this example is not close to what happened – it would be better described as someone coming to an AA meeting and asking what alcohol is while owning a business selling it.

It is not at all that I would not wish to be polite to someone who is asking for help or, even just asking. As long as it is done honestly. This Carrie lied – pure and simple. She was asking a false question to set up people to respond, a classic trolling tactic.
