It's only a matter of time before someone will penetrate your systems; one way or another. Just because you're paranoid doesn't mean that someone isn't out to get you. You can talk about ethics until you're blue in the face but every now and then, someone will try to test their skills against the system, not so much out of malice but out of curiosity.
I know someday my systems will become infected. I don't lose any sleep over it because I've done my best to minimize the consequences and I take all the avilable possible precautions but, as I say, it's just a matter of time. I figure that if it can be done it will be done and like all the rest of us, I'll just have to muddle through it as best I can.
I notice your link to Paul Mah's blog. I find most of his stuff overly melodramatic alarmist and worse, usually four to six weeks, if not months, too late or out of date. Maybe it's due to his location but I do find that I'm usually already aware of most things he writes about and after a while he just becomes tedious and/or repetitive. Usually I'll give his stuff a little glance and then delete it. Haven't really learned anything new from him. In fact when I do acquire new things it's usually from people such as yourself and Col as well as a few others.
