We have an rss feed of jokes to spice up your site, whatever site it is. You can use it for filling:

It is updated twice per day, an example output can be seen here:

We're working on a site with a ton of newsitems, all adult related so you can submit newsworthy stuff to get published anywhere the rss feed is used. It is actually already done, but we're finetuning it.
