Last year, Hell made headlines when a hacker dumped the personal details and sexual preferences of almost 4 million users of the hookup site Adult Friend Finder. The data dump was only discovered months after the hack, forcing Adult Friend Finder to admit the breach. A couple of weeks later the site's administrator and founder, known as "Ping," disappeared, prompting rumors that he had been arrested. Even though Ping resurfaced a few days later, the website closed down shortly after in mid-July. (It was then briefly resurrected before going offline for good.)

Now, an old forum moderator has relaunched the site, which looks and feels exactly the same way—and it's still only accessible by using the anonymizing software Tor.

"Hell is now public," the new forum administrator, nicknamed "HA," wrote in a post. "Anyone can share the HELL URL where they see fit."
