Well, there was a hacker, who I won't address by name anymore, who managed to bypass all the various protections that NF had - and redirected it to a different forum called Maddox, apparently to cause trouble. NF wasn't the only forum affected, as the forum at animesuki.com, which shared the same server, was also similarly hacked and redirected.
It took three days for NF to be fixed, but mbXX, the guy who hosts our server, wanted to take the time to figure out a better security system and to ensure that it wouldn't happen again. So it took a week for things to return back to normal.
The reason NJT didn't want a thread about it to go any further here was because many people were using it as a platform to throw out curses at the hacker - and we just didn't want any kind of bashing going on here. It encouraged a kind of spamming frenzy that was more of a negative nature.
...and that being said, I've deleted that thread. It's in the past now. ^_^
