Have e-rewards got wise to HotSpot Shield? I'm overseas and I've not had a survey that hasn't "expired" immediately I click on it for at least a month, probably more, even though I get at least 5 emails from e-rewards each week. HotSpot Shield used to solve the issue of being abroad, but it doesn't seem to make any difference now, unless there's some other reason why I'm having problems. Any ideas?
