Dammit dude, youa re missing the point. Mods are members who now have control over the posts. Admins are the guys at the servers. Yea, so they are excellent at overclockign and seemingly dont know other stuff about computers. The admins who run the servers most likely dont know much about overclocking, but they run the SERVERS, therefore know what they are doing. The simple fact is is that it was hacked. There are going to be people at that forum who know a shiteload, and are quite proficient when it comes to hacking, and something pissed them off (maybe got banned) therefore hacked it.
Did I mention they are using VBuilletin and NOT PHPBB?
It looks as though you are simply looking for a way to shoot someone down, IE. XS. Why? Simple fact that they got hacked, and you are jumping to conclusions that they are morons who dont know how to set up a server? Members reflect NOTHING on the admin. If they did, because of Dale, Larry would be considered the biggest idiot of all time... But he's not.
There is no system that is 100% hacker proof, and there is NO WAY you can know EVERY SINGLE WEAKNESS of your system. If you did, than it could be hacker proof, but that simply does not exist. Flaws always exist everywhere, and it is virtually impossible to find every single one of those flaws and plug them.
