1) Photos with the watermark of a reputable porn site
2) Photos which include a note about where the photo comes from. Examples: “Hey this is my beautiful asshole. My name is Janie and I’m 32 and I love your blog.” Or “We’re a funloving Dutch couple and we run a blog together. Here’s a photo that my wife wanted to share.”
Anything else I’m going to delete because I’m only comfortable posting photos if I know for sure that they’re appropriate. Thanks so much!
