Do not data mine my emails. Do not read or look at them. They are none of your business

Yahoo actually linked my Yahoo Mail account to one of my social media accounts (Flickr) and then without my permission attached a photo of me from that account, and for almost a year anybody who received mail from me also received a photo of me which was linked to my Flickr account. It wasn't until I BCC an email to my iCloud email account that I realised it was happening.
How is this legal?
Couldn't agree more. Get the word out. Demand respect for ordinary citizens and also privacy.
