I would take pictures of them taking pictures and report. That is not ok. As long as u are doing what their contract says they can't sue. Was that child registered with them? Did u keep that child even though u found him privately but he was registered can u keep him? I don't know how that works. If he was with the agency but u got them on ur own and the agency didn't send him to u then i would think its ok to keep him. But on the other hand u might want to leave that child and wipe ur hands clean of them and get children on ur own
