In the reply to email about the photo they stole from my facebook without permission/credit, my college said they took down the photo (and though I still see it's online in one section of their site, I don't think it's worth pursuing anymore).
They also replied that photos cannot be distributed, paid or unpaid, to the kids in pictures or their parents as they risk losing eligibility. They also noted "This is where we got the photo from" (exact words,they got the pic from one of the kid's facebook profiles), implying they looked at my facebook, whatever was displayed publicly, and decided posting there was a form of distribution
What sort of comeback should I write in response to this? I would not like to show any signs that imply "You win, I lose" because that would be feeding the trolls. Also should I set my photos to private and friends only, in such a way only people who are friends with me can see them?
