I understood this as part of Facebook a long time ago and don't really use instagram. I tried it, but don't like it at all. I purchased snapseed when it was app of the week a while back and really enjoy using it and my regular camera. I am sure many people don't know the facebook policy and post at will. I know I have things out there on facebook that I wouldn't want them to use as marketing, but I have my watermark on anything I think might be used for something.

Something I have been wondering...what about when they sell something to advertise and there is a person in that photo without a model release or property without a property release? What are the legal ramifications of that?
