There is no software out there in the world that works on everything. Whether it be anti-virus, a firewall, or anything else that a computer may run. And the fact that the software is in place, doesn't mean that it can just be left to work on it's own. If you look at Punk Buster, there are a number of tools available to help admins catch cheaters that the system is not catching. Like any other piece of software, it needs to be manually kept up to date, and the available tools must be utilized in order to provide the best possible protection. Please realize that there is no "magic way" to install software on a server, and then just live in a totally cheat free enviroment. It is this way in online gaming, just as it is in everything else in the world. The purpose of pbbans.com is to work together in order to provide the best protection we can by making sure that we all keep eachother up to date on new cheat issues and anti-cheat software, and that we share our catches with eachother to keep hackers off our servers once they are caught so they cannot just upgrade to a new undetectable cheat each time they are caught with the one that Punk Buster has figured out or added to their code.
As far as Punk Buster not being worth a "ratt's hairy ass"? I would have to disagree since the amount of cheaters on our servers has decreased exponentially since we enabled and updated it properly along with using the MBI here at pbbans.com. And through the use of the various tools available in Punk Buster, more cheats are removed all the time. You just have to understand how to properly configure and utilize the system in order to notice the big difference it makes. While not perfect, our clan's opinion of it is that it is the best tool out there presently to achieve as cheat free servers as possible.
