This is something I have been meaning to do for a while now and today I have finally gotten around to doing it. All files and images marked as "Adult-only" are now blocked from viewing for non-members, and those members who have specifically chosen to block the content. By default adult-only content is blocked on the site. In order to view adult-only content on the site you need to be a registered member, logged in, and toggled the adult-only view settings in your preferences.
The reasons behind this are typical and common place across the web; to protect "minors", censor inappropriate content for people at work, and help those people who don't want to accidentally stumble across this content.
At the moment it is only the uploaders of files and images who can toggle the "Adult-only" content flag so I ask uploaders to use their own mature judgement on using the flag. If your file uses or shows nudity or quite graphic violence then please turn that adult-only flag on. I'm sure you're tired about some people moaning about not wanting to see your content in their game so this is the perfect way to give them no excuses and stop them complaining for good.
