bagatelle

In another forum there was a case of forum administrator being friends with a forumer, who got banned. This banned member wanted to talk to another forumer, who hadn't put up his email public in his profile, so the banned forumer asked his friend, the administrator, for the email. Admin gave him the email address, this forumer had used at registration to the site, without forumer's permission.

Later these friends had a fallout and to hurt his admin friend the banned member revealed chatlogs, which show admin giving out the email address - eventually someone posted about it in the forums. The violated forumer had never been contacted via that email though by the banned member, but someone else did after seeing his email forwarded off-forums among certain members - this way the forumer, who's info had leaked, became aware of it.

I would assume as a default that the registration information to any forum would be safe, meaning only the admins or mods, who possibly can view the details, wouldn't pass this information forward. Imo this goes without saying.

The site has personnel, who work as site employees, but the forum is run by volunteer admins and mods, who don't get paid. Who's responsibility?

How strongly do you feel about this? How would you react? I'm not very knowledgeable about the legal aspects about email privacy in forums, but I would assume my email is not getting forwarded without my consent.
