Try to upload something else tomorrow. Doujins aren't well received here.
And I really hope that nobody approves them.

I've seen quite some doujins on danbooru.

That doesn't mean it's welcomed.
I'm only telling you. It's up to you if you want to upload more of that stuff, but don't think that it'll be easily approved (at least that's what I want to believe).

A single page should be fine, if you upload the best or funniest part of it, just to let people know it's there. And then they can download and view it.

But as for doujins that are only online, those are fine.

well ok then, I won't upload any more of it. Delete it then.
if you look on the internets you may find it to dl :)
