It's up to us members to ensure the site stays safe and fun to use. Blogs, media, users and comments may all be reported using the report function displayed at each location. If we abandon ship every time something strange is posted, before giving the moderators time to react, then the pervs get the upper hand. It is a far better thing to stay and mould the Naktiv community ourselves.
We also have a support group where experienced members lurk, waiting to assist you. If you're ever confused about this, you can ask yourself whether you would leave Faceache because someone posted something you didn't like. This usually focuses the decision making apparatus, and the usual response is to report the item and move on down your newsfeed.
Please use the report facilities with consideration.
