Well, they nailed me quite well, even while using a browser other than Chrome, Safari or Firefox. Cool test. A little unsettling what info is gathered in just a few seconds, right?
Just an FYI. I just tested this using a TOR browser while I was still logged in here - purposefully. I was thinking it may cause something to "surface" (two sites at the same time). The TBB came back completely clean and good to go. TOR can make you lazy because they really know how to configure their browser stuff!
No, you are not identifiable, as there are 60 user(s) who look like you among the 1120 users we tested so far: (had to allow page scripts & turn Adguard extension off and I block third-party cookies....so, whats the point)
