Looking back on the experience I think the problem is they have no idea what kind of website their automated tool will be applied to so it has to work for all, no matter how complex. That means it would be massive overkill for my little sites.
That means you have to have one, but I am not sure many/anyone really cares exactly what it says. I suspect it is a leftover from early internet days when visitors were not aware of how they could be tracked and profiled from information their browser made public. Internet surfers are much more aware now. They also care less and worry less about it.
I plan to write a short statement that says I don’t collect any information myself and the only ad service I use is Google AdSense. Then I will link to the Required Content page and tell them to go there if they need to know more. Hopefully, that will be enough to keep everyone happy.
