Probably using a combination of G+ and GA to check your 'history' to see the activity is like a normal human. Visits a couple news sites each day, checks their gmail, searches for random crap randomly, GA registered a 'conversion' for some company = probably a human
- emcrazyone 12y agoI was thinking they may be looking at how long it takes for a user to click the "I'm not a robot" link. A robot would probably load the page and quickly, without delay, send the HTTP POST but I have to imagine they thought of this already and bots writers would quickly add a sleep() call in there at some point... Yea, I wonder about their internal logic too.
