First off. You put your crappy pictures of you and your friends showing each other your butt cracks while doing shots of Everclear on the top of the water tower on Instagram. Because you just needed all of your friends to know what a jackass you are. Those one hundred and fifty pictures of your cat that you felt you wanted to makes sure your nephew saw? Yep. You posted them.
You also posted these things to pretty much the entire internet. There is no way around that. It's time to get real cozy with the idea that one you digitize your precious things...nobody gives a shit if it's "yours:" anymore. At that point, "private" is a joke. Nobody cares if you might, possibly, want to make a little money off it, or if you might object to someone else taking your intellectual property and make a tidy profit off it.
Does that bother you? Hmmm- sounds familiar.
Sucks when the shoe's on the other foot, huh? Maybe the folks that got your picture from Instagram might pay you for another one, huh? Maybe?
