Well, there's a lot more to it than just that. I understand the fines and I think they need to be paid, just not by me.
Googling for secure forums mostly brings up sites where people are discussing secure forums, and it seems there's no real such thing as a fully secure forum. Forums with open source are easier to hack, but they all have security holes reguardless. I want a new forum, but I'm paranoid of the past repeating itself.
Phpbb seems the most looked down on and I see more votes for vBulletin, but I can't afford vB. I guess I'll try Simple Machines Forum. I'm still not sure though.
