Does anyone know how their beacons get around Gmail's tracking buster? (https://gmail.googleblog.com/2013/12/images-now-showing.html https://gmail.googleblog.com/2013/12/images-now-showing.html)
- detaro 11y agoWhat's there to get around? the gmail proxy fetches the image, which tells GitHub that the email has been opened, which is all they need to know. The proxy does protect against leaking the IP address, cookies and potential code injections, but not against the signal "image requested by user".
