Alex,
As someone who spent years being cyberstalked, I can sympathize with you. It's no fun to be constantly accused of untrue things -- there is always the question of whether to engage and feed the asshole's vanity or stay silent and let the lie go unchallenged. This is the real power of the cyberstalker. You are, in some ways, damned it you do and damned if you don't. Fortunately, people like this quickly demonstrate to everyone what jerks they are, so folks stop taking them seriously about anything. But with enough perserverance they can eventually insert their untruths into the collective unconscious, so they need to get publicly swatted down from time to time.

I hope to see you next week.

John
