All mature content (art, discussion, links) must be tagged with a specific "Mature" tag.
This tag and everything posted with it is hidden by default, and you must request access to that content. By requesting it, you imply that you are allowed to access such content in your jurisdiction.
You can request access to mature content and the ability to post such content by commenting below. It will serve as a to-do list for me, and I'll delete the posts as I give out the tags.
Only moderators and other members of Mature group will be able to see your Mature tag (the small icon next to your avatar).
