I would say not since we don't store any info anywhere except on the user's device, or browser's local storage. Also, users are choosing to share this info if they want, with their friends.
I was obviously joking, but it's nice to know that you treat this seriously.
Hah sorry, I am new to HN and I didn't want to sound arrogant by assuming that you were joking. But your comment made me to double check so thanks!
