Although there is potential for abuse, the fact that BA came out first to say they were doing it, gives (IMO) a reasonable image of transparency.
What will come of it... to be seen.
Image search for my name reveals a tombstone as the 5th image.
Thanks BA, I've got a good chance of being greeted with a preview of my death when I fly.
After all, BA won't be employing 50,000 new staff to check that images are appropriate, or even related to the correct person. How many "Mike Smith's" will there be?
If you want to "know me" know that I want you to leave me the fk alone.
Am I allowed to publicly criticize my experience as a customer with such or such airline without getting served a cold meal the next time or without getting booted?
While observing your country's laws you should be entitled to your opinions, and it shouldn't matter if it's privately or publicly. Unfortunately companies apply not the law when they "asses" you as a customer but their own arbitrary judgement: it's rarely fair, and sometimes even barely legal.
