Posts asking for pics

Does anyone else get paranoid about the posts asking for certain kinds of pics? Like, let me see your ultrasounds, your husband/boyfriend with your baby, your baby bumps, etc? I just keep thinking about creepy men with pregnancy fetishes, or the teenagers that have weird online hobbies involving fake instagram/tumblr posts (cyber kidnapping). I'm sure most of the posts are started with good intentions, but I'm still scared to participate lol.
