For example, amazon. If an affiliate code were to be inserted that paid DDG for purchases made through DDG, would that be a privacy violation? We had a bit of discussion about this here: http://duck.co/topic/amazon-associates
My previous thought was yes, but now thinking through it I think there is a distinct case of whether you go through a third party or not, and also it matters what info is sent. That is, if you have a third party handle it and they see your personal info, then that is a violation. If there is not a third party (just Amazon and DDG) then that becomes a lot less of a violation, I think depending on what is seen.
The data piece is that if you just see a check and no personal information, I'm not sure that is a violation. Anyway, would love to know your thoughts.
