Bot mill people are very aware of headless browsers being an effortless solution to mimic a browser, but not that efficient.
The amount of ram and so a bots spends to do a single click can truly hurt their bottom line.
Top tier collectives I heard of use own C/C++ frameworks with hardcoded requests and challenge solvers, and in-depth knowledge of anti-botting anti-fraud techniques used by the opposing force. If DoubleClick finds a brand new performance profiling test, and send it out in the JS code in one in 1000 requests, expect those guys to detect it and crack it within 24 hours.
They have no objective of getting through captchas, just having their number of valid clicks in double digits.
