I'd like to request this too. Give us the ability to hide all doujin content and make it a global setting that works across the whole site. I know some people like fan-made stuff, but I have zero interest in it. Plus it really clutters up the site since there seems to be like 39473979357 doujin releases per month lately. For example, browsing the calendar when looking for official releases is a huge pain in the butt.
I've trained my eyes to just block out anything orange on the site, but a real option would be way better.
