If I have secure, important, client documents on my machine or open while I played UO, it'd just be too much of a risk that a dump of whatever might go somewhere when it shouldn't.
That's not really how it works.
It doesn't scan documents...or files on your hard drive. It looks at what programs are running on your machine...not the contents of your drive, or your docs.
For fun, while you are sitting at your PC and out in windows, hit Ctrl-Alt-Del at the same time. It will bring up your task manager...you can see the same things PB sees, basically.
Do you see anything private there?
If they did require PB, just close any other programs that you would not want anyone seeing you run before you launch UO.
Again, it cannot see your documents. It cannot read your passwords. It cannot send anyone any information about you, except what programs and processes you were running when you started UO, while you were running UO, and when you closed UO. That's it.
I don't think PB would actually solve the problems UO has...mostly because the problems UO has are problems that cannot be solved by passive means.
Anyone can write a script program if they know Visual Basic, or several other programming languages. PB, or any other detection program for that matter, cannot disallow you running Visual Basic. Do you know how many apps out there use VB?
Also, there are slight changes that can be made to how 3rd party programs load (I did over simplify it in an earlier post) that can work around something like PB.
Punk Buster would simply not be effective at stopping the hardcore cheaters. It would simply make it difficult for people that wanted to run a simple script or just didn't know that they should use a newer version of whatever they were running.
With that said however, the so-called privacy issue comes off as paranoia...or a smoke screen for cheaters.
Saying "I don't trust Punk Buster...but I gave Electronic Arts my name, address, email address, IP address, and Credit Card number" is rather ... well ...silly.
EA, just like the creators of Punk Buster, has a professional reputation to maintain...and that reputation will make them or break them when it comes to their clients.
If suddenly everyone with a UO account had their CC#s stolen, and it was traced back to UO...would you still keep a CC# on file with EA???
Probably not.
If Punk Buster stole someone's personal info...and it was reported that it happened, no one like EA would ever use them again...and they would go out of business.
Think about it like this...your bank has more information on you than almost anyone. But you trust them with everything you have.
Privacy is not a valid reason to not want Punk Buster...unless you have something to hide.
