Sure, I have nothing to hide and I don't watch porn so my results would be very boring and mostly about cats.music and stuff I am trying to find info on for my eBay business.
I've got an incredibly tame search history and a very basic browsing history but $10k honestly isn't THAT much money to me at this point so no, I wouldn't. It would need to be a life changing number.
100% yes for £10k. Nothing illegal in there and nothing to be embarrassed about. Human beings watch pornography, so fucking what. Gimme that money, that's a new car right there.
