In the latest Zap (dev only for now), you can auto-pixelate images by connections who you don't trust to tag their not-safe-for-work stuff. Let's face it - not everybody sees titties as a bad thing, but for some of us merely having them scroll by on our screens can cost our jobs. Hover to reveal. (I haven't yet checked this with a phone or tablet - which _might_ take some additional work since hover is a bit weird on handheld devices). This is a core feature and is set by setting a 'censor' flag on the connection. It also applies to comments on their posts by other third parties so if you set it on a group you'll catch everything you receive from the group. A hidden config controls how much pixelation to apply if you don't like the default.
