PHP is just ugly. And Shiichan has undocumented features, BBCode, very serious comments all over the place, horrible logic. Take a look at it and barf.

CGI/Perl is just notorious for causing issues. Especially kareha insisting on having the index.html in the same location as kareha.pl. The moderation could also maybe need some better ACL. I know, trust your moderators and stuff, but it doesn't feel right.
