The Lower Hudson Journal News infamously published a list of licensed gun permit holders in two counties in New York, including names and home addresses.
The reaction included retaliatory publication of Journal News staff home addresses and phone numbers, widespread condemnation even from other journalists, and ultimately, legislation barring such publication. The Journal News now has taken down the list, but only after more than a million views.
One other form of retaliation, reported first at Legal Insurrection, was the hacking of the Journal News user database, including subscribers, and the posting on a website and at Pastebin. We never provided links, for many of the same reasons we did not publish personal information someone tried to post in the comments about the home and family addresses of the Chair of Gannett, the parent company of the Journal News.
I can report, however, that as of this morning, the Pastebin and other location of the hacked databases no longer contain the stolen information:
(It is likely the information now is posted elsewhere by people who copied the databases. Do not attempt to post links in the comment section. Anyone who does that will be permanently banned from commenting.)
Update 1-29-2013: I received an email from someone apparently affiliated with the one of the sites, who indicates that the site is back up and was only turned off because of presumed lack of interest and now is back up. The person said that the Journal News did not take down the site; my post referred to the Journal News taking down the original list of gun owners after 1 million views, not to the Journal News taking down the site where the databases were posted.
