er, no the casual internet user such as myself, uses an ISP to get to the internet, IPS dont like this sort of activity going on, hence they boot people when they detect it there are many ways to get around this, anyone with the knowledge and inclination would be able to screw around with whatever on your "hack proof" site if they so pleased
I created a 100% hacker proof site once. It was hosted on my PC that wasn't connected to the internet and was locked in a 10 inch thick titanium casing. You can never have a site that's 100% secure you can only minimise the risk by taking precautions. If you look at your site as being totally secure it already has a major weakness.
sorry john but i have a friend who has hacked almost every site he has been to, even the ones that claim they are unhackable. So i doubt yours is unhackable. no offence though.
