>>23153This is honestly one of the biggest reason why I got a pass in the first place.
Fact is that when you fill in a Google captcha form in your browser, not only are the images you've selected sent to their server for verification, but also a "secret ID" of your captcha challenge.
Scariest part is that when you then submit the post, 4chan's severs checks with Google to verify that your challenge was actually solved.
Of course 4chan doesn't provide Google with any information about your post directly, but that isn't needed since they receive your captcha's secret ID along with the exact time you submitted your post.
So Google can (read: will) find the exact post you made on 4chan easily by simply looking for a post with a date that matches the time that your captcha was verified.
So now they have your IP, your post, browser information, and of course your associated Google accounts.
This is true for their "legacy captcha" as well.
