I could go on ad nauseum about all the potential non-software ways that could go a long way in helping someone intent on breaking the law break the law, but the common thread in all your hypotheticals is people who want to break the law will find ways to break the law. If you want to help fix our current societal issues that drive people to want to break the law, that's another story. We have armed guards, large vaults, and cameras in banking centers, but that doesn't stop people from trying to rob the bank. We have federal laws and regulations protecting people's mail, but that doesn't stop identity thieves from going into your mailbox or digging through your trash for banking statements. If a creepy stalker spots their ex's car driving down the road, what's stopping them from following her/him home? "But how would they find out what car they are driving?" you may rebute, well who decided to post what brand new car they drive on facebook? At some point, people have to take responsibility for the information they put out there about themselves. I wouldn't call into a radio show and blurt out my full name and address for everyone to hear before I gave my opinion. I think this leads to a different issue -- why is appointment management software asking for personally identifiable information? Maybe we could make a distinction -- if you deal with PII, then these standards should be placed upon you.
