To explain a bit about this donation thing: there are two ways you can donate to Doujin-World. Both ways will be explained in detail so you can choose or you wish to donate at all and how you want to do that. Of course donating is just an option, you are not obligated to donate in any way.
Orginal Donating Option
The Orginal Donation form is through Hentai Key. You can help Doujin-World by signing up for a GT key and in return you get access to our webdownloads and access to all other Hentai Key GT sites which all contain tons and tons of content. From pictures to movies more then 3TB of content spread over the GT sites. As you can imagine this is a huge collection you get and you help Doujin-World with it. So it's like a win/win scenario. You help us and you get tons of Hentai content in return.
To donate you can this way you can go to the Sign Up page.
Secondary Donating Option
As not everyone is willing to sign up for Hentai Key for their own private reasons and that's fine. We made it possible for those that still want to contribute to Doujin-World with helping us fund our bots, website and translators. This basically is a donation form that allows you to donate $5 or whatever you feel we deserve through multiple donations. Mind you that at this moment people that donate this way don't get anything special other then a +v in our IRC channel. We are working on making a special thanks for donating section on the site that allows people that donated this way to get a special release by D-W. One not released on IRC.
To donate this way you can go to the donation page at Anime Ryu.
