1. Build an archive.

  - Create a private archive blog.
  - Make a comprehensive list of tags you plan to use and search for suitable posts to archive. These will be your "regulars" and will be a reliable source of quality posts that won't ever disappear.
  - Do this occasionally even after building a large enough archive
  - The larger this archive becomes, the more variety your blog will have.
  - Have a queue-friendly theme, perhaps with a button that adds a post directly to the queue without leaving the page.

2. Create a second private blog and set up its queue.
 
  - Before stacking and processing your queue, you should calculate how many posts you will want to make per day. The queue can attempt to publish a post up to 50 times a day. This means your maximum queue per day can be no more than fifty posts in length.
  - Consider posting 48 posts between 12AM and 11PM; giving a steady two posts an hour forever. This appeals to all timezones, and each day will have its own theme.
  - Consider dividing weeks up imaginatively. I suggest 4 theme days per week, split up by an "anything goes" melting pot of variety porn between each theme day.

2. Use the second private blog as a feed for your porn blog.

  - Your porn blog will follow only this feed.
  - You should queue posts directly from the dashboard, starting from the bottom of the latest set of unqueued posts.
  - Remember to take theme suggestions and submissions for variety days.
  - Congratulations, you now have a fully functional porn blog with minimal maintenance involved!
