But I know of online sites, especially email, who will refuse information to Police for even people accused of serious crimes.
Naeblis,
They may refuse it, but once an easily obtained court order is issued for the production of such evidence, failure to comply results in contempt sanctions, up to and including incarceration. How many site operators are willing to go to jail for their principles in this regard?
The bottom line is, those who think it's ok to intentionally inflict harm upon others by disclosing the private details of others online without their consent deserve to be deactivated on this forum and also deserve whatever adverse legal consequences their conduct causes. If it happened to me, Simon's deactivation of the perpetrator's account on this forum would be the least of that person's worries.
