Well, I suppose out of the 10 posts listed on the main page, there will probably be about 8-10 porn autoposts.
I'd have it autopost relevent news or something it could fetch online.. but nothing is quite fitting.
By the way, I will be making a way for people to select not to view the autoposted stuff. In the mean time, try bookmarking the text-only version for use at locations wehre you can't have a full size pornographic image loaded.
