Maybe, maybe not. From time to time google forces me to prove I'm not a robot because of unusual search queries. Either my queries are unusual or I have an infected computer. The thing is, it also happens to me on my iPhone.

Or, maybe they feel I'm not pulling my own weight, seeing as I rarely ever click on adds. They probably need more monkeys to feed the beast so I get selected to train their AI beast.

Edit: It could also be that I'm always running on incognito mode.
