If one is viewing Pugski from a location where others are also using the same network, might one see ads related to what the others are viewing? Likewise, might they be seeing skiing related ads, even though they aren't skiers? When I'm viewing Pugski from different locations, I get a different set of ads, even though I browse the same sites from each location. When at home, if I turn off an ad I'm not interested in, I never see it again, but in other places, ads that I try to turn off keep coming back anyway. I came to believe it was because others are going to places that bring those ads back to the common network that everyone uses.
