I've worked in their customer care (recently quit). There is such a thing as false positives, little old ladies who don't know the difference between a proxy and a flux capacitor. And the company line for someone calling about a VPN error? Do **not** help or advise them in anyway except telling them to undo what they've done whatever that was, and call the ISP to help find what default settings should be. Next thing you know, you've got a rep from the ISP calling in because an entire IP block is getting flagged, and nobody can actually cite any particular instruction, marker, or standard for why it's getting flagged and what needs to be done about it. I can tell you this, the corporation looks to weigh the undue hardship of innocents in dollars, and that ought to be incompatible with some ethical systems.
