In the ongoing arms race, we're likely to see simple things like this sort of check result in a handful of detection systems that look for "set a cookie" or at least "open the page in headless chrome and measure the cookies."
Does anyone have any proof of this?
I mean they have access to a mind-blowing amount of computing resources so to they using a fraction of that to improve the quality of the data because they have this fundamental belief (because it's convenient for their situation) that scale is everything, why not use JS too. Heck if they have to run on a container full a browser, not even headless, they will.
Navigate, screenshots, etc. it has like 30 tools in it alone.
Now we can just run real browsers with LLMs attached. Idk how you even think about defeating that.
