Really? I should trust their "delete" option?
Already collected personal data can be deleted by the user through their Google Account.
I am more likely to invest trust in a second hand car dealer than Google. I reckon any delete request will simply mean they will mark the data as no longer visible to that user. I found the same with LinkedIn, btw, I once deleted the whole account, but when I recreated it half a year later it was suspicioulsy accurate in suggesting people to connect with.
The fun part came when I also created a fake user, ostensibly working at some well known companies - it was interesting to see the requests coming in for someone who did not even exist.
I am thinking about possibly grabbing a face of thispersondoesnotexist.com and setting upa couple of fake personas, each on a different country of origin (operating via VPN), just to see if I can get a handful of nuts into their gearbox.
