Geezus, I undergoed something similar, not to that extreme though (we never got hacked, but spammed to the extent that I had to load a yesterday forum backup). The only way they probabaly hacked into the forum was an exploit, they A) Were not running the newest version of the BBS; B ) An exploit was found for the newest release of the BBS; C) They brute forced an Admin's password. This is a shame that this had to happen since the ZSNES board was very popular, I even browsed there quite a few times.
